Auxiliary surgical suture line in-out device

Abstract

The invention discloses an auxiliary surgical suture line in-out device. The auxiliary surgical suture line in-out device is characterized by comprising an outer cannula, a needle core and a lead needle bar, wherein a coil (9) is connected with one end of the lead needle bar. The outer cannula comprises a cannula cap (2) and a hollow cannula (3), and an upper hole (1) of the cannula cap (2) is penetrated up and down through a lower hole (4) of the cannula (3). The needle core comprises a needle core cap (5), a needle core body (6) and a needle tip (7), the needle tip (7) is arranged at the bottom end of the needle core body (6), and the needle core cap (5) is arranged at the top end of the needle core body (6). The auxiliary surgical suture line in-out device disclosed by the invention has the advantages and beneficial effects of operation procedures with simplified suture, more easily controlled needle outlet points inside and outside chest walls, more simplified intrathoracic operation procedures and greater-degree reduction of complications caused by suture of the traditional suture needle to ensure that a patient is safer.

Description

technical field [0001] The invention relates to a surgical suturing device, in particular to an auxiliary surgical suturing thread inlet and outlet device, which belongs to medical surgical instruments. Background technique [0002] Due to the limitations of the anatomical structure of the human body and the size of the surgical incision, it is difficult to insert and remove the needle during suturing in certain parts of the human body; the following uses a chest wall incision as an example to illustrate. [0003] The chest closure suture of the chest wall incision usually requires intermittent sutures across the bony chest wall across the intercostals. The usual method of suturing the chest wall incision is to hold the tweezers in the left hand and the needle holder in the right hand to hold the suture needle, insert the needle from the outside of the chest wall on one side of the chest wall incision, and penetrate into the chest cavity; Hold the suture needle; release the...

AI Technical Summary

Problems solved by technology

[0007] One is that metal suture needles are relatively short, and it is very difficult to suture the large-span intercostal intermittent suture of the chest incision; it always makes the suture difficult and even awkward for the surgeon;

[0008] The second is that the process of completing the stitching operation is relatively cumbersome, and the left and right hands need to be repeatedly inserted into the chest cavity, and the operation in the chest cavity is mostly done under blind vision and by experience;

When suturing the two ends of the incision, due to the narrower operating space, the poorer compliance of the bony chest wall and the more limited field of vision, the traditional closed-chest suture method is used to complete the cross-section through cumbersome "needle insertion" and "needle extraction". Closing the bony chest wall incision with interrupted intercostal sutures becomes more uncomfortable and "more awkward", and requires blind vision and experience to complete the suture process, adding more blindness, more time-consuming and laborious , or even unsatisfactory suturing, resulting in unsatisfactory chest closure effect, severe cases may even cause puncture of lung tissue, intercostal blood vessels, etc., resulting in continuous postoperative air leakage, alveolar fistula, incomplete chest closure hemostasis, postoperative bleeding, progressive hemorrhage, etc. Serious postoperative complications such as thoracic

[0012] When suturing small incisions in the chest, also because the incision becomes smaller (about 10 cm), the compliance of the bony chest wall becomes smaller, so small that it is difficult for the surgeon to put one hand into the chest cavity, and the operation space is significantly limited. The field of view is significantly limited, and it is almost more difficult to satisfactorily complete the suture of the intercostal intermittent nodules of the bony chest wall by using the traditional closed-chest suture method that requires the cooperation of two hands and repeatedly inserting and inserting the needle into the thoracic cavity. Small incision surgery is time-consuming and labor-intensive in steps that do not require too much attention, and even unsatisfactory chest closure can cause more serious complications such as puncture of lung tissue and intercostal blood vessels

[0013] Generally speaking, the current conventional suture method for closing the chest incision has always had certain disadvantages. It not only prolongs the suture time for closing the chest incision, but also may affect the suture effect and even endanger the patient's life; thoracic surgeons have been looking for improved methods. method
