Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a stapler device for nasal endoscopic dacryocystitis surgery. Background Art

[0002] The treatment of dacryocystitis mainly relies on surgery, and endoscopic dacryocystorhinostomy is the mainstream surgery for dacryocystitis. Problems such as poor stoma formation and closure during the operation will lead to poor drainage or failure of the operation again. Therefore, opening the dacryocystorhinostomy during the operation and opening it effectively within a certain period of time after the operation play a vital role. In the existing endoscopic dacryocystorhinostomy, the doctor sutures the lacrimal sac mucosa and the nasal mucosa through endoscopic nasal operation, which is difficult to operate. At the same time, the tear duct "U"-shaped tube solution is also used in the stoma-related materials. However, this tear duct tube solution is prone to tearing of the upper and lower lacrimal puncta, lacrimal canaliculus inflammatory reaction, and other late inflammatory polyps around the dacryocystorhinostomy, resulting in poor anastomosis effect. Therefore, how to design a nasal endoscopic dacryocystorhinostomy anastomosis device with a simple structure, no need for sutures, and good anastomosis effect has become the focus of research in this field. Utility Model Content

[0003] In order to solve the above technical problems, the present application provides a stapler device for dacryocystitis surgery under nasal endoscopy, which has a simple structure, and the locking tongue of the stapler passes through the lacrimal sac mucosa and nasal mucosa and is locked with the lock buckle. The lacrimal sac mucosa and nasal mucosa are pressed by the two inner walls of the U-shaped stapler, and no sutures are needed to sew the lacrimal sac mucosa and nasal mucosa, eliminating the complicated suturing operation. After the U-shaped stapler is stapled, the dacryocystostomy can be fully opened, reducing the closure of the stoma during the recovery period and improving the surgical healing effect.

[0004] The technical solutions provided in this application are as follows:

[0005] A stapler device for nasal endoscopic dacryocystitis surgery comprises: a U-shaped stapler, wherein the two side walls of the open end of the U-shaped stapler extend outward to form a bent portion for contacting the clamp arms of the implantation clamp; and a locking tongue and a locking buckle structure are respectively provided on the two inner side walls near the open end of the U-shaped stapler.

[0023] The embodiments of the present application are written in a progressive manner.

[0024] See also Figure 1As shown, the present application discloses a stapler device for nasal endoscopic dacryocystitis surgery, comprising: a U-shaped stapler 10, wherein the side walls of the opening end of the U-shaped stapler extend outward to form a bent portion 1 for fitting and contacting with the clamp arms of the implantation clamp; a locking tongue 2 and a locking buckle 3 are respectively provided on the two inner side walls near the opening end of the U-shaped stapler.

[0025] The anastomosis device of the present application is used for performing a one-time anastomosis of the incised lacrimal sac mucosa and nasal mucosa during nasal endoscopic surgery for dacryocystitis. The anastomosis device is used in conjunction with an implantation forceps. The open end of the anastomosis device is wrapped with the lacrimal sac mucosa and nasal mucosa. Pressure is applied by the implantation forceps, and the locking tongue of the anastomosis device passes through the lacrimal sac mucosa and nasal mucosa and locks with the locking buckle. The lacrimal sac mucosa and nasal mucosa are pressed by the two inner walls of the U-shaped anastomosis device; no sutures are required, and the use and operation are easy; at the same time, after the anastomosis, the dacryocystostomy can be fully opened, reducing the closure of the stoma during the recovery period and improving the surgical healing effect.

[0026] Furthermore, the U-shaped stapler is made of a degradable elastic material, preferably a degradable stent material used in existing surgeries. The stapler is made of fully degradable materials and does not need to be removed after surgery. It is practical and convenient, and reduces secondary operation damage.

[0027] Furthermore, the bent portion is an inverted U-shaped structure formed with the side wall of the stapler. The arms of the implantation forceps are inserted into the inverted U-shaped structure, which facilitates the application of pressure to the U-shaped stapler and regulates the opening and closing of the stapler's opening end; the lacrimal sac mucosa and nasal mucosa are extended into the U-shaped opening of the stapler, and with the help of the implantation forceps, the locking tongue passes through the lacrimal sac mucosa and nasal mucosa and then locks with the locking buckle. The lacrimal sac mucosa and nasal mucosa are pressed by the two inner walls of the U-shaped stapler, and no sutures are required. The tip of the locking tongue is set as a thorn to facilitate the penetration of the lacrimal sac mucosa and nasal mucosa during surgery; see for details. Figure 3 Schematic diagram of the anastomosis device used in conjunction with the implantation forceps.

[0028] The stapler device of the present application further includes an implantation forceps 20, which has a rotatably connected joint scissor fork 4, one end of which is connected to a handle 6; the other end of the joint scissor fork is connected to a clamp arm 5, and the two clamp arms are divided into a first clamp arm and a second clamp arm. The joint scissor fork is a scissor fork 4 with a rotating joint; see Figure 2 The implant clamp structure is shown.

[0029] Furthermore, the arm of the implantation forceps is provided with a receiving slot 7 for facilitating the insertion and placement of the bending portion structure, see Figure 4 The bent portion of the stapler is inserted into the accommodating slot of the clamp arm of the implantation forceps, which helps prevent the stapler from loosening during use, and the implantation forceps applies pressure to the U-shaped stapler more steadily and evenly.

[0030] Furthermore, the first clamp arm and the second clamp arm are parallel to each other.

[0031] The anastomosis device of the present application is used for performing a one-time anastomosis of the incised lacrimal sac valve and nasal mucosa during nasal endoscopic surgery for dacryocystitis. After anastomosis with the U-shaped anastomosis device, the dacryocystostomy can be completely opened, reducing stoma closure during the recovery period and improving the surgical cure rate.

[0032] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
