Problems solved by technology

Insufficient fixation of the mesh can easily lead to loosening or falling off of the mesh. At present, the fixation of the hernia repair mesh usually adopts the method of clinical suture, that is, the mesh is fixed on the tissue through sutures at multiple positions of the mesh, but this kind of suture The efficiency of the operation method is low, the operation time is increased, and the operation level of the doctor is high, and the suture effect is not easy to guarantee, and the patient recovers slowly

Embodiment 1

[0048]An automatic bending medical supplement fixing stapler is used in this embodiment.figure 1 The automatic bending medical patch fixing staple is a special fastener. The automatic bending medical patch fixation is composed of two parts of the implant 1 'and the bent portion 2', and the front end of the implant 1 'has a pointed 1-1' for piercing the tissue, the implant 1 1 The 'is provided with barb 1-2' for stabilizing the tissue, the bending portion 2 'is provided at the tail of the implant 1', and the bending portion 2 'has at least two bending arms 2-1' The columnar structure is formed between the circumferential adjacent bending arms 2-1 'by the thin wall 2-2', since each bending arm 2-1 'has automatic opening after the thin wall 2-2' is broken. The bending stress, thus cutting the thin wall 2-2 ', and each bent arm 2-1' can be opened to the outside. According to the structure of the above automatic bending medical patch fixing nail, the hitting of the patch fixing staple is...

Embodiment 2

[0055]An automatic bending medical supplement fixing stapler is a basic structure of this embodiment, and the basic structure is in Example 1.Figure 11 As shown in the present embodiment, the above-described clamping slide 3-4 is a diaphragm having a first jaw head 3-1 and a second clamp head 3-2 rear end, which includes The slant groove segment 3-4a and the horizontal slot 3-4b, the leveral slots 3-4a, and the horizontal groove section 3-4b are connected, and the leveral groove segments 3-4a are located behind the horizontal groove segment 3-4b, the chute segment The 3-4a is opposite to the tilt direction on the first clamp head 3-1 and the second clamp head 3-2. With this diaphragm chute, the slider 2-2b can be moved in front and rear in front and rear in the diaphragm, and the slot segment 3-4a can be opened, and the sliding pin 2-2b can be Control the first clamp head 3-1 and the second clamp head 3-2 are completely closed, the horizontal groove section 3-4b can provide the cutt...

Abstract

The invention discloses an automatic bending type medical patch fixing nail firing device, which belongs to the field of medical devices. The device for firing medical patch fixing nails of the present invention includes a handle assembly, a sleeve assembly, a clamp head assembly and a reset mechanism, and the movable handle in the handle assembly is used to push the clamp head push tube in the sleeve assembly to move to drive the two clamp heads To close or open, use the cam profile of the cam to drive the cutter push rod in the sleeve assembly to move the cutter at the front end to cut off the thin wall at the tail of the patch fixing nail, so that the pliers head can close and clamp the patch fixing nail , and cut off the thin wall of the tail of the patch fixing nail, one firing action can complete the positioning and clamping of the pliers head on the patch fixing nail and the cutting action of the thin wall of the tail of the patch fixing nail successively or simultaneously, realizing automatic bending A series of actions of clamping, thin-wall cutting, implantation and releasing bending and fixation of the medical patch fixing nails have an ingenious and compact structure, flexible and convenient operation, and safe and reliable use.

Description

Technical field[0001]The present invention relates to a firing operation instrument for a patch fixing staple, and more particularly to an automatic bending medical patch fixing stapler.Background technique[0002]With the continuous development of material medicine, more and more new materials enters the medical field as a defect in the human body parts of the human body. Medical patch is a human tissue repair material, which is widely used in general surgery, mainly used in the repair of all kinds of hernia, such as inguinal hernia and incisional hernia. Due to the particularity of the 气, the patch needs to have a strong tension strength and is not soft, and the patch also needs to have an appropriate shape according to the patch tissue position to facilitate stabilizing in the human tissue.[0003]The fixation of the patch in human tissue is the key to hernia repair surgery, and its fixed effect directly affects the success or failure of surgery, and has a critical impact on whether ...
