A locking and limiting medical soft tissue suture device

Abstract

The invention relates to a medical soft tissue suturing device with a locking and limiting function. The medical soft tissue suturing device comprises a shell part, a soft tissue suturing needle part, a propelling part and a limiting part, and the limiting part limits the course of the propelling part to control the course of the soft tissue suturing needle part; the shell part comprises an upper shell body and a lower shell body, a long hole for the propelling part to move is formed in the upper shell and provided with a baffle, and the baffle covers part of the long hole close to the soft tissue suturing needle part. By using the limiting part, it is avoided that in the propelling process, due to nonuniform force application, propelling is excessive, or propelling is insufficient and re-propelling is needed, operation accuracy and efficiency are affected. The baffle has the effect of preventing a foreign object from falling into the lower shell body. The distance of the needle part is shorter, does not touch deep layer of soft tissue easily in the using process, and therefore is prevented from damaging nerves and bones.

Description

technical field [0001] The invention relates to a medical suturing device, in particular to a locking and limiting medical soft tissue suturing device which can accurately control the position of an advancing thimble through a limiting device, is more convenient to use, and does not damage the deep layer of soft tissue. Background technique [0002] Existing suturing devices do not have a dual or multi-linkage propulsion mechanism. After the needle passes through the tissue, it is pulled back to catch the front hair anchor, which is a one-time consumption. However, it is often necessary to pass through the soft tissue multiple times during the operation. Determine the optimal position, so the existing design does not meet the needs of actual clinical operations. [0003] When the thimble is used for propulsion, the existing propulsion generally uses subjective feelings, and then uses printed scales to meet the needs of a fixed amount of propulsion, which is imprecise, has no...

Problems solved by technology

[0005] 1. In this patent application, the advancing process of the soft elastic limit propulsion part is controlled by the protrusion and the corresponding limit hole. During the propulsion process, it is easy to advance due to uneven force transition or insufficient propulsion stroke, and it needs to be propelled again, which affects the precision and efficiency of surgery;

[0006] 2. In this patent application, in the space where the long hole is close to the stop, water or blood during the operation will enter the lower shell and damage the lower shell, thereby affecting the accuracy and life of the entire device. In addition, there are The possibility of instruments used in surgery falling into the lower case;

[0007] 3. In this patent application, the distance from the limiting groove to the top of the needle is not further limited. In the specific implementation process, if the distance from the limiting groove to the top of the needle exceeds a certain range, the needle is likely to touch the soft tissue The deep layer is easy to damage the nerves and bones. In addition, if the length is not enough, it is not easy to complete the suture safely and efficiently.
