Scratch-proof stitching needle for anastomat

Abstract

The invention discloses an anti-scratch stitching needle for an anastomat, and belongs to the technical field of medical instruments, the anti-scratch stitching needle comprises a stitching needle seat, the inner side of the stitching needle seat is sleeved with a titanium stitching needle, and a threaded groove is formed in the end, located on the inner side of the stitching needle seat, of the titanium stitching needle. According to the invention, through the mutual cooperation of the designed structures such as the flow guide tube, the nail needle seat, the titanium nail needle, the threaded groove, the smooth connecting piece and the elastic medicine feeding box, the device can be suitable for the condition that the thickness condition of the stapling machine body tissue is relatively complex, so that the titanium nail needle can be prevented from sliding along the machine body tissue surface in the bending process due to the too long titanium nail needle; the elastic medicine feeding box can achieve a certain buffering effect and a certain pressure reduction effect, and the situation that after the titanium nail needle is bent, the titanium nail needle enters the body tissue due to the fact that high pressing force exists between the nail needle base and the body tissue, and secondary damage is caused is prevented; a medicine which is easily dissolved in an organic solvent can be injected into the elastic medicine feeding box through the feeding port, and the medicine is beneficial to recovery of wounds of the patient.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a scratch-resistant staple needle for a stapler. Background technique [0002] The stapler is the first stapler in the world and has been used for gastrointestinal anastomosis for nearly a century. It was not until 1978 that the tubular stapler was widely used in gastrointestinal surgery. It is generally divided into one-time or multiple-use staplers, imported or The domestic stapler is a medical device that replaces the traditional manual suture. Due to the development of modern technology and the improvement of production technology, the stapler used in clinical practice is reliable in quality, easy to use, tight, and suitable for tightness, especially its fast suture. It has the advantages of simple operation, few side effects and surgical complications, etc., and also enables the tumor resection that was unresectable in the past. [0003] The stapler has ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that the existing staple needles for staplers still have some defective use problems in the process of use, in general, in order to ensure that the staple needles can penetrate body tissues of different thicknesses, the staple needles The length of the stapler is usually set to be very long. When encountering thin body tissues, it is easy to cause insecure sutures, and the longer staple stitches will be along the surface of the body tissue during the bending process. Sliding, and easy to scratch, when encountering body tissue with uneven thickness, it is easy to embed the staple needle into the body tissue, and cause the problem of secondary injury, and a kind of anti-scratch staple needle for stapler is proposed
