Description
Technical Field
The invention belongs to the field of suturing devices for medical supplies, and particularly relates to an operation suturing device.
Background
Basis cranii depression is a disease occurring in the skull-cervical junction area, and is generally characterized by that on the basis of congenital deformity of basis cranium base and upper cervical vertebra, the atlantoaxial dislocation is combined, and the dentate process of the dentate vertebra is sunk into the macropore of occipital bone, and the brain stem and medulla oblongata are pressed, so that the related clinical symptoms are caused. When diseases or lesions in the cranioconjunctival junction area cause high spinal cord and brainstem compression, decompression or internal fixation surgery is often performed anteriorly, and oral or nasal access is one of the commonly used surgical approaches. Since the nasal cavity cannot accommodate too many instruments, special instruments must be designed to perform the procedure, which is quite different from the conventional open surgery. After decompression is finished, the closing of the incision is a key technical problem, and no special suturing instrument for the nasal endoscope is required in the markets at home and abroad. Therefore, the current surgical method generally adopts the U-shaped reverse of the mucosal flap, and the treatment is carried out by using a method of biological protein glue after the operation is finished. The treatment method can not close the surgical wound surface tightly, and once the conditions of dura mater damage, cerebrospinal fluid leakage and the like occur in the operation, intracranial infection is easy to occur, and the death of a patient is caused.
In open surgery, when suturing, two instruments are generally required to cooperate to complete the suturing operation of tissues such as mucosa or skin, and no device for realizing the suturing by a single instrument exists. When the auxiliary operation is performed through the nasal endoscope, only one operable instrument can be generally placed in each nostril, because the endoscope occupies the nostril at one side, two conventional surgical instruments cannot be simultaneously placed in the nasal cavity to complete the suture of the mucous membrane, and only the nostril at one side can be used by the suture instrument. To perform the operation of suturing the mucosa in the nostril, a device which can complete the suturing action by a single instrument must be developed.

As shown in FIG. 1, a surgical suture instrument comprises a suture needle 7 and a suture holder 1, wherein a damping ring 71 is arranged at the head of the suture needle 7, an eyelet 72 for penetrating a suture thread is arranged at the tail of the suture needle 7, and the tail of the suture needle 7 is clamped in the suture holder 1.
In one specific embodiment, as shown in FIG. 4, the damping ring 71 is in the shape of an inverted hook. Specifically, when the needle is inserted into the mucous membrane tissue on one side by the holder, the needle body cannot be easily retracted and can only be advanced, and the suture needle 7 is called a one-way retaining suture needle 7. In the process of operation, firstly, a suture thread is penetrated through a needle eye 72 at the tail part of the suture needle 7, then the suture needle 7 is fixed on the suture holder 1, the suture needle 7 is controlled to penetrate through a mucous membrane tissue in the visual field of an endoscope, meanwhile, the damping ring 71 partially penetrates through the mucous membrane tissue, and the suture needle 7 cannot exit because the damping ring 71 is in a barb shape and has a certain blocking effect after penetrating through the mucous membrane.
In a specific embodiment, the cross-section of the tail of the needle 7 is polygonal. Specifically, in order to enable the suture needle 7 to be clamped on the suture holder 1 more firmly, the tail part of the suture needle 7 is designed to be polygonal; meanwhile, the needle clamping end 21 of the suture holder 1 is matched with the shape of the installation position of the suture needle 7, so that the probability of falling off of the suture needle 7 in practical application is reduced.
In one embodiment, the needle 7 has a circular arc shape with a gauge radius of 3.5mm to 15mm, and more specifically, the gauge has a radius of 3.5mm, 5mm, 6mm, 7mm, 8mm, 9mm, and the like. In order to meet the requirements of different specifications of surgical operations, various specifications of suture needles 7 are designed.
As shown in fig. 2, the suture holder 1 is provided with a needle clamping rod, one end of the clamping rod 2 is a needle clamping end 21 for clamping the suture needle 7, the other end of the clamping rod 2 is a moving end 22 moving along with the button 6, the sleeve 3 is wrapped outside the needle clamping rod, one end of the handle inner core 5 is connected with the sleeve 3, the other end of the handle inner core 5 is movably connected with the button 6, and the periphery of the handle inner core 5 is fixedly connected with the handle 4 for facilitating taking; when the button 6 is rotated, the fixed end of the clamping rod 2 drives the needle clamping end 21 to move, when the clamping rod 2 moves out of the sleeve 3, the suture needle 7 clamped at the needle clamping end 21 can be taken out, and when the clamping rod 2 moves in the sleeve 3, the suture needle 7 is installed at the needle clamping end 21. Specifically, as shown in fig. 3, the inside of the clamping rod 2 is solid, the needle end 21 at the front end of the clamping rod 2 is composed of a left split part and a right split part, and when the clamping rod 2 enters the sleeve 3, the sleeve 3 presses the needle end 21, so that the suture needle 7 in the needle end 21 is tightly fixed, and the shape of the needle end 21 is matched with the shape of the installation position at the tail part of the suture needle 7. In a particular embodiment, the knob is screwed onto the handle core 5. The connecting part of the sleeve 3 and the handle inner core 5 is welded by argon arc welding. Specifically, because the sleeve 3 and the handle core 5 are fixedly connected in the actual sewing process, an argon arc welding mode is used for the connection to be more compact.
The operation stitching instrument comprises the following steps: firstly, fixing a suture needle 7 on a suture holder 1, and threading a suture line; delivering the suture holder 1 from one nostril to the nasal cavity to reach the operation position and finding out the mucous membrane edge needing to be sutured; under the visual field of an endoscope, firstly, the suture needle 7 penetrates through a mucous membrane tissue at one side to be sutured, after the damping ring 71 completely penetrates through the mucous membrane and is clamped with the mucous membrane tissue, the button 6 is rotated, so that the moving end 22 drives the needle clamping end 21 to move towards the suture needle 7, and the suture needle 7 fixed at the needle clamping end 21 is released after the needle clamping end 21 is not subjected to the extrusion force of the sleeve 3; then the suture holder 1 is withdrawn, the medical universal tool holding forceps are used for extending into the nasal cavity, the suture needle 7 is pulled out of the mucous membrane, and the suture thread passes through the mucous membrane tissue while pulling out the suture needle 7 because the suture thread is already penetrated into the needle eye 72 before the suture needle 7 is arranged on the suture holder 1, thereby completing the suture process of the mucous membrane tissue on one side; the suture needle 7 is clamped on the suture holder 1 again outside the nasal cavity, and the instrument is extended into the nasal cavity again; repeating the above operation, passing the suture needle 7 through the opposite side mucous membrane, and pulling out the suture needle 7 by using a holding forceps; taking down the suture needle 7, and knotting the suture thread outside the nasal cavity; pushing the thread knot into the nasal cavity by using a knot pusher to finish a first operation knot; knotting again outside the nasal cavity, and pushing into the nasal cavity by a knot pusher to complete a second operation knot; repeating the above processes as required to complete the surgical knotting process; with the aid of an endoscope, trimming is completed by using microscissors.
In summary, the special suturing device for suturing the mucous membrane in the nasal cavity is designed to prevent the suturing needle 7 from retreating due to stress through the specially designed damping ring 71, after the suturing needle 7 penetrates through the mucous membrane tissue, the suture holder 1 releases the suturing needle 7, and the suturing needle 7 is taken out from the nasal cavity by using other tools, so that the operation is completed. The invention solves the problems in the prior art, thereby realizing the minimally invasive suture process and improving the success rate of the operation.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
