Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of staplers, and in particular to staplers with a soft rubber head staple cartridge assembly. Background Technology
[0002] A stapler is a medical device used to replace manual suturing. Its main working principle is to use titanium staples to separate or anastomose tissue, similar to a stapler. Depending on their application, they can be mainly divided into skin staplers, digestive tract (esophagus, stomach, intestines, etc.) circular staplers, rectal staplers, circular hemorrhoid staplers, circumcision staplers, vascular staplers, hernia staplers, and lung cutting and suturing staplers. The staple cartridge assembly is an essential component of a stapler. During surgery, it is often necessary to use the stapler's jaws to dissect involved tissues or insert the stapler's jaws into tissue gaps. Currently, the surgeon usually needs to first use surgical forceps to open the tissue gap before inserting the stapler jaws to complete the anastomosis. This operation has significant drawbacks because the staple cartridge end is thicker than the other end, and the staple cartridge head is made of hard plastic. When the staple cartridge is inserted into the tissue gap, it can easily abut against fragile tissues, causing trauma and discomfort to the patient. Summary of the Invention
[0003] The technical problem to be solved by this utility model is: in order to solve the problems existing in the background art, a stapler with a soft rubber tip is provided. By adding soft rubber to the end of the stapler head for use, the problem of bumping into the tissue and causing trauma is avoided, thereby improving the overall safety of the stapler and facilitating its widespread promotion and use.
[0004] The technical solution adopted by this utility model to solve its technical problem is: a stapler with a soft rubber head staple cartridge assembly, including a stapler body, a staple cartridge assembly installed at the end of the stapler body, and a rubber head assembly installed at the end of the staple cartridge assembly; the rubber head assembly includes a rigid staple cartridge end, the rigid staple cartridge end has an elliptical end and a sloping upper end structure, a staple cartridge groove is formed on the sloping upper end structure of the rigid staple cartridge end, and a soft rubber head is inserted into the staple cartridge groove.
[0005] Furthermore, in the above technical solution, the shape of the soft rubber head corresponds to the structure of the rigid staple cartridge end, and the inner side of the soft rubber head has a cavity structure with an opening at the lower end; this design is to achieve the wrapping and fixing of the soft rubber head at the rigid staple cartridge end, so as to achieve the effect of flexible contact.
[0006] Furthermore, in the above technical solution, the staple cartridge groove has a T-shaped structure with an open top, which facilitates the snap-fit connection of the soft rubber head.
[0007] Furthermore, in the above technical solution, a protruding soft rubber buckle is provided on the inner top surface of the soft rubber head, and the soft rubber buckle is also T-shaped; this facilitates the snap-fit connection of the soft rubber head.
[0008] Furthermore, in the above technical solution, the soft rubber head is fixed by being embedded in the nail cartridge groove with a soft rubber clip; this facilitates free loading and unloading by the user.
[0009] Furthermore, in the above technical solution, the soft rubber head and the soft rubber buckle are an integral structure.
[0010] The beneficial effects of this utility model are: the stapler with soft rubber head assembly proposed in this utility model avoids the problem of tissue injury by adding soft rubber to the staple head, thereby improving the overall safety of the stapler and facilitating its widespread promotion and use.

[0019] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0020] In this application, the stapler body 1 and the staple cartridge assembly 2 are models that are currently used in the market, and the soft rubber head 5 is selected and installed according to the actual situation.
[0021] See Figure 1-6 The diagram shows a stapler with a soft rubber tip staple cartridge assembly, including a stapler body 1, a staple cartridge assembly 2 installed at the end of the stapler body 1, and a rubber tip assembly installed at the end of the staple cartridge assembly 2; the rubber tip assembly includes a rigid staple cartridge end 3, which has an elliptical end and a sloping upper end structure, and a staple cartridge groove 4 is formed on the sloping upper end structure of the rigid staple cartridge end 3, and a soft rubber tip 5 is inserted into the staple cartridge groove 4.
[0022] The soft rubber head 5 has a shape corresponding to the rigid staple cartridge end 3, and its inner side is a hollow structure with an open bottom. The staple cartridge groove 4 has a T-shaped structure with an open top. A protruding soft rubber buckle 6, also in a T-shape, is provided on the top inner surface of the soft rubber head 5. The soft rubber head 5 is secured by the soft rubber buckle 6, which is inserted into the staple cartridge groove 4. The soft rubber head 5 and the soft rubber buckle 6 are an integral structure.
