Description
Technical Field
The invention relates to the technical field of medical subcutaneous soft tissue suturing instruments, in particular to a subcutaneous soft tissue suturing device and a degradable metal suturing nail.
Background
At present, manual suturing is still adopted for muscle suturing, the suturing speed is relatively slow, the operation and anesthesia time is prolonged, the risk of postoperative infection in the operation is increased, and the clinical requirements on convenient and quick suturing instruments and methods are gradually increased. Although some subcutaneous tissue anastomats are applied to the operation at present, most of the subcutaneous tissue anastomats are designed aiming at specific purposes (such as lumen anastomosis and the like), and the effective, free, beautiful and quick suturing effect on the wound surface with irregular damage or the muscle tissue with rich elasticity is difficult to achieve; in addition, the existing subcutaneous anastomat has the defects that the volume of the nail outlet part is huge, the visual field of an operator is blocked or partially blocked in the operation, the accurate positioning of the suturing position is difficult, the suturing precision and efficiency are low, and the suturing is too tight and too dense. The suture tissue is excessively excessive due to low suture precision, so that the suture tissue has adverse reactions such as inflammation, necrosis, formation of fistula tract and the like, and the necrotic tissue needs to be removed by a secondary operation or the fistula tract suture needs to be performed.
The sutures currently used are divided into two categories, non-absorbable and absorbable, wherein the non-absorbable sutures are perpetuated in the muscle tissue as foreign bodies, and the rejection reaction caused by the non-absorbable sutures may cause a series of pathophysiological reactions, such as: inflammation, infection, scarring, etc., which are the main causes of post-operative muscle tissue dysfunction or slow recovery. If the adverse reactions need to be eliminated, the wound needs to be cut again to take out the suture, and the existing absorbable suture is mainly made of high polymer materials, has low rigidity, cannot be made into a suturing nail with self-nailing capability, is only suitable for low-efficiency suturing and cannot realize high-efficiency tissue nailing.

4) an included angle d between a horizontal line of the end part of the opening and a connecting line of the tip is 110-160 degrees;
5) the height b of the top protrusion is 1-4 mm.
The working principle of the invention is as follows: when the muscle or subcutaneous tissue is sutured, firstly, the tip of the stapling track 21 between the stapling track front cover plate 22 and the stapling track rear cover plate 23 of the stapler is extended into the position to be sutured, and the tip at one side of the stapler is used for hooking the muscle or tissue at the corresponding side to be positioned; under the action of the nail pushing spring 33, the foremost nail 31 enters the position of the nail closing track 21; then the operator presses the pressing block 15 downwards to push the nail pushing plate 13 to move downwards, after the lower end of the nail pushing plate 13 contacts with the suturing nail 31, the suturing nail 31 is sent to the position to be sutured along the suturing track 21, after the suturing nail 31 with sharp tips reaches the arc-shaped section of the suturing track 21, the muscle or tissue to be sutured is nailed in, and simultaneously, the bending deformation is generated along the suturing track 21, so that the tips are crossed to form a closed ring shape when entering the muscle or tissue.
After the stitching nail 31 reaches the required stitching requirement, the operator releases the pressing block 15, the nail pushing plate 13 returns to the position before stitching under the action of the restoring force of the return spring, and meanwhile, the next stitching nail 31 moves to the position of the stitching track 21 along the nail feeding track 35 under the action of the nail pushing spring 33, so that the next stitching nail is ready for the next stitching.
The invention has the beneficial effects that: the subcutaneous soft tissue stitching instrument realizes the effects of continuous nail feeding and rapid stitching through the nail pushing mechanism 10 and the nail storage cabin mechanism 30, effectively saves the stitching time of muscle or subcutaneous tissues, and effectively reduces the surgical trauma and infection risk; meanwhile, the sharp end of the nail outlet button at the front end of the anastomat is designed, the visual field of an operator is not shielded, the anastomosis requirements of various irregular broken muscle ends or subcutaneous tissues are met, and the sharp end of the anastomat is nailed to the track 21 and designed in an arc degree mode, so that the muscle or the subcutaneous tissues can be sutured accurately, safely and efficiently; and the suture nail 31 is prepared by using biodegradable magnesium-based or zinc-based material, so that the muscle or subcutaneous tissue is effectively sutured, and is degraded within a certain time, thereby reducing post-operation inflammation and rejection reaction.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
