Description

Technical field:

[0001] The utility model relates to the field of surgical instruments, in particular to a push rod forceps. Background technology:

[0002] At present, endoscopes are a kind of medical instrument for examining human organs and performing surgery on diseased tissues. Endoscopes are divided into rigid endoscopes and flexible endoscopes. When performing flexible endoscope examinations and surgeries, a transparent mucosal suction sleeve is put on the top of the endoscope, and then the snare is passed through the endoscope's own equipment channel. The snare is used to extend the transparent mucosal suction sleeve to cut the diseased tissue in the diseased area, and then the cut diseased tissue is adsorbed into the transparent mucosal suction sleeve through the endoscope's adsorption capacity to complete the surgery.

[0003] In actual applications, it is found that some lesion tissues are too large and have different shapes, while the commonly used transparent mucosal suction sleeve is an integrated cylindrical shape with a single structure. Therefore, the inner and outer shapes of the transparent mucosal suction sleeve need to match it in order to accommodate the lesion tissue; secondly, the snare through the channel of the flexible endoscope must extend out of the sleeve of the transparent mucosal suction sleeve. Due to the narrow space of the sleeve, the loop at the end of the snare is too small, and the lesion tissue with too large volume is not suitable. In view of the above findings, the surgical method is changed, and the snare is placed on the outer wall of the transparent mucosal suction sleeve to avoid the problem of the snare loop being too small. During the operation, the snare loop is removed from the transparent mucosal suction sleeve. However, there is still a lack of corresponding technology for medical instruments suitable for improved surgery, especially tools for removing the snare loop. In order to ensure convenience, hygiene, and timely use, this tool needs to meet the requirements of low cost and disposable use. The end of the existing medical forceps is a hard straight tube with a complex structure and can be used multiple times. Not only can it not be bent with the flexible endoscope, but it also needs to be disinfected for the next use, which cannot meet the requirements. Utility model content:

[0024] In the figure: an external hanger 1, a push rod device 2, a sleeve 3, a sleeve assembly 3.1, a tape 4, a rod body 5, a clamp head 6, an opening 6.1, an inner groove 7, a protrusion 8, a groove 9, and a ring 10. Specific implementation method:

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figures 1 to 7 As shown, a push rod forceps comprises an external hanger 1 and a push rod device 2, wherein the external hanger 1 comprises a sleeve 3 and an adhesive tape 4 adhered to the outside of the sleeve 3; the sleeve 3 is adhered to the outer surface of the endoscope by the adhesive tape 4;

[0027] The push rod device 2 comprises a rod body 5 and a clamp head 6 integrally formed at the end of the rod body 5. The clamp head 6 is annular and has an opening 6.1. The clamp head 6 is put on the ring 10 of the snare by using the opening 6.1. The push rod device 2 can be made of polyethylene material and has softness.

[0028] The shaft 5 is movably inserted into the sleeve 3, and the forceps head 6 and the shaft 5 enter the patient's body along with the endoscope. The shaft 5 is slid in the sleeve 3 to push the push rod device 2 to move, so that the forceps head 6 pushes the loop 10 of the snare to be removed from the transparent mucosa suction sleeve, and then the push rod device 2 is retracted, and the loop 10 of the snare leaves the forceps head 6 from the opening 6.1.

[0029] There are several external hangers 1. In order to prevent the shaft 5 from being loosely positioned on the upper limit of the endoscope, multiple external hangers 1 can be provided.

[0030] The outer surface of the sleeve 3 is provided with an inner groove 7 along the length direction to match the outer surface of the endoscope. Usually the outer surface of the endoscope is a curved surface, so the inner groove 7 matching the outer surface of the endoscope is added. The sleeve 3 fits the outer surface of the endoscope through the inner groove 7 to ensure a stable connection.

[0031] The sleeve 3 is formed by two sleeve assemblies 3.1 matched together. The diameter of the pliers head 6 is customized according to actual needs. In order to prevent the rod body 5 of the push rod device 2 from being unable to penetrate the sleeve 3 from the end, the sleeve 3 is designed to be matched with two sleeve assemblies 3.1 to reduce interference and improve ease of use. The adjacent side walls of the two sleeve assemblies 3.1 are respectively provided with mutually matching protrusions 8 and grooves 9. When the two sleeve assemblies 3.1 are matched together, they can be positioned by splicing the protrusions 8 and grooves 9 between each other to avoid misalignment.

[0032] Two parallel cuts are made along the two ends of the adhesive tape 4 toward the center, and the two ends of the adhesive tape 4 are divided into three parts. Any part of the two ends of the adhesive tape 4 is adhered to the external hanger 1. When the sleeve 3 is composed of two sleeve components 3.1, as shown in FIG. Figure 5 As shown, the shaft 5 is placed in the sleeve 3, and the two sleeve components 3.1 are matched. The two sleeve components 3.1 are first wrapped and bonded together through any part of the two ends of the tape 4, and then bonded and fixed to the endoscope through the remaining parts of the two ends of the tape 4.

[0033] The clamp head 6 is in a "G" shape.

[0034] The clamp head 6 is in a "C" shape.

[0035] The novel technology fixes the external hanger 1 on the endoscope and enables the push rod device 2 to move on the external hanger 1, so that the forceps head 6 of the external hanger 1 follows the endoscope into the patient's body, and the forceps head 6 pushes and pulls the forceps head 6 to remove the snare ring 10 from the transparent mucosal suction sleeve during surgery. When the snare ring 10 has been sheathed on the diseased tissue during surgery, the push rod device 2 needs to be removed, and the opening 6.1 of the forceps head 6 can be used to detach from the snare ring 10, or the electric heating resection method of the snare can be used to cut off the forceps head 6 to detach, so as to meet the surgical operation. At the same time, the external hanger 1 and the push rod device 2 have simple structures and can be made into disposable products to reduce costs.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
