一种简易的自动外科手术缝合器A Simple Automatic Surgical Stapler

技术领域technical field

本发明涉及外科手术缝合器械技术领域，特别是涉及一种简易的自动外科手术缝合器。The invention relates to the technical field of surgical suturing instruments, in particular to a simple automatic surgical stapler.

背景技术Background technique

现今外科手术大都需要用对伤口进行缝合，现今的外科手术缝合器械大都结构简单，一种为单一的针体结构，需要医护人员动手缝合，另一种为辅助缝合的结构，不论哪种缝合器械和缝合方式，缝合效率都比较低下，严重影响手术的缝合进程，为此，我们提出一种外科手术缝合器械。Most of the current surgical operations need to suture the wound. Most of the current surgical suturing instruments are simple in structure. One is a single needle structure that requires medical staff to suture manually, and the other is an auxiliary suturing structure. No matter what kind of suturing equipment And the suturing method, the suturing efficiency is relatively low, which seriously affects the suturing process of the operation. For this reason, we propose a surgical suturing instrument.

中国CN201610078051.5，公开了一种外科手术缝合器械，包括第一支架和针头，第一支架通过侧面的两个连接柱和第二支架连接，针头的末端设有针孔，第二支架通过伸缩装置和安装板连接，安装板的表面设有滑轨，在滑轨的表面活动卡接有直线电机，直线电机的表面设有中空的连接杆。该外科手术缝合器械，采用手持式手柄来进行缝合，便于医护人员的使用，采用直线电机在滑轨上做直线运动，并且针头在曲柄和摇杆的带动下在连接杆的滑槽中做往复运动，从而实现对伤口的缝合，医护人员只需要将缝纫线穿到针孔中，就可以手握该器械利用控制器对缝合进程进行控制，自动化程度较高，缝合效率高，减少了医护人员的劳动量。但是其在投入使用之后，缝合的伤疤较为明显，并且外观难看。China CN201610078051.5 discloses a surgical suture instrument, including a first bracket and a needle, the first bracket is connected to the second bracket through two connecting columns on the side, the end of the needle is provided with a needle hole, and the second bracket is stretched The device is connected with the installation board, the surface of the installation board is provided with a slide rail, a linear motor is movably clamped on the surface of the slide rail, and a hollow connecting rod is provided on the surface of the linear motor. The surgical suturing instrument uses a hand-held handle for suturing, which is convenient for medical staff to use. It uses a linear motor to make a linear motion on the slide rail, and the needle reciprocates in the chute of the connecting rod under the drive of the crank and rocker. Movement, so as to realize the suturing of the wound, the medical staff only need to pass the sewing thread into the pinhole, and then hold the device and use the controller to control the suturing process. The degree of automation is high, the suturing efficiency is high, and the medical staff is reduced amount of labor. However, after it is put into use, the stitched scars are more obvious and the appearance is ugly.

中国专利CN201280041937.2，一种用于开放性和/或内窥镜手术的外科手术缝合器械，其被配置为在第一钳构件与第二钳构件之间向后和向前传递双头外科手术针，该钳构件各自包括夹持装置、以夹住外科手术针的各自的针头，其中第一和/或第二钳构件通过第一偏置力被偏置于打开位置。所述器械进一步包括操作装置以操作第一和第二夹持装置，其中操作装置包括第一操作元件，其被具有第二偏置力的一个或多个第二弹簧构件偏置于正常位置，其中第一偏置力小于第二偏置力，以致在第一操作元件上施加驱动力将首先导致第一和第二钳构件朝向彼此的运动，并随后导致操作装置的驱动。但是其在使用时，缝合效率相对较低。Chinese patent CN201280041937.2, a surgical suturing instrument for open and/or endoscopic surgery, which is configured to pass the double-headed surgical suture backward and forward between the first jaw and the second jaw Surgical needles, the jaw members each comprising gripping means to grip a respective needle head of the surgical needle, wherein the first and/or second jaw members are biased to the open position by a first biasing force. The instrument further comprises operating means to operate the first and second clamping means, wherein the operating means comprises a first operating element biased to a normal position by one or more second spring members having a second biasing force, Wherein the first biasing force is smaller than the second biasing force such that application of an actuating force on the first operating element will firstly result in movement of the first and second jaw members towards each other and subsequently actuation of the operating means. But when it is in use, the stitching efficiency is relatively low.

中国CN201010145542.X，公开了用于切割组织并向组织施加一个或多个外科手术缝钉的管状缝合器械。器械包括多种形式的砧座锁定系统，砧座锁定系统设计为选择性地防止砧座相对于缝合器械的缝合头部轴向移动。一个实施例采用了细长齿条，细长齿条选择性地与锁定齿轮啮合，以防止细长齿条和用于轴向定位砧座的调节轴进行轴向运动。其他实施例采用了与细长齿条配合的齿轮组件。锁定构件由容纳齿轮组件和细长齿条的手柄组件可移动地支撑。锁定构件被构造为选择性地啮合到齿轮组件，以便最终防止齿条和调节轴的轴向移动。虽然该管状缝合器械解决了外科手术缝合效率以及缝合后的伤疤外观难题的技术问题，但是其整体结构较为复杂，生产成本相对较高。China CN201010145542.X, discloses a tubular suturing instrument for cutting tissue and applying one or more surgical staples to the tissue. Instruments include various forms of anvil locking systems designed to selectively prevent axial movement of the anvil relative to the suturing head of the suturing instrument. One embodiment employs an elongated rack that selectively engages a locking gear to prevent axial movement of the elongated rack and an adjustment shaft for axially positioning the anvil. Other embodiments employ a gear assembly that mates with an elongated rack. The locking member is movably supported by a handle assembly housing the gear assembly and the elongated rack. The locking member is configured to selectively engage the gear assembly to ultimately prevent axial movement of the rack and adjustment shaft. Although the tubular suturing instrument solves the technical problems of surgical suturing efficiency and the appearance of sutured scars, its overall structure is relatively complicated and its production cost is relatively high.
