Disclosed is an endoluminal surgery instrument, comprising an operating device (1) and a handle (2). The operating device (1) comprises an operating portion (11) and a connecting portion (12). The handle (2) is provided with a connecting rod (3), the connecting rod (3) has a tip portion, and the tip portion of the connecting rod (3) is connected to the operating device (1). The connecting rod (3) comprises a hollow sleeve rod (31) and a core rod (32) movably arranged in the sleeve rod (31), and the core rod (32) can be controlled to stay in different positions by means of operating the handle (2) so as to enable the operating device (1) to open or close. During an operation, the operating device (1) is placed in a lumen (D) via an incision (B), the tip portion of the connecting rod (3) enters the lumen (D) along a puncture point and is fixedly connected to the connecting portion (12) of the operating device (1), and the handle (2) is then operated in vitro such that the operating portion (11) can be controlled to implement a corresponding surgical operation. The diameter of the tip portion of the connecting rod (3) is less than 3 mm, such that the puncture point does not need to be stitched up, thereby reducing injury to the body of a patient. Moreover, since the operating device (1) can be detached from the handle (2), the size of the operating device (1) is not limited by the diameter of the connecting rod (3), such that it is possible to perform the surgical operation in vitro more conveniently.

An intracavity surgical system is disclosed, which includes an operating device, a connecting rod and a handle. Wherein, the operating device includes an operating instrument and a connecting portion. During the operation, the operating device is placed in the cavity through the incision, and then the tip of the connecting rod enters the cavity along the puncture point and is fixedly connected with the connecting part of the operating device, and the other end of the external connecting rod is fixedly connected with the handle, and then through the The handle controls and adjusts the operating instrument outside the body to achieve the corresponding surgical operation. The invention can reduce the damage to the patient's body, and at the same time, it can more conveniently perform the operation outside the body and improve the success rate of the operation.

The invention relates to a preparation method of a general-purpose anterior tooth opener, comprising: (1) taking a pair of standard upper and lower jaw dentition models, and recording the occlusal relationship, and then placing the upper jaw on the model; step (2) adjusting the jaw Opening degree, engrave the wax shape of the anterior tooth area mouth opener, and make the anterior tooth area resin mouth opener; step (3) measure and design the size of the anterior tooth area resin mouth opener, and obtain the data of the universal anterior tooth area opener; step (4) Convert the data of the designed universal anterior teeth mouth stretcher into data recognized by a 3D printer, and print out the universal anterior teeth mouth stretcher. The preparation method of the present invention is simple and easy, and the cost is low, and can be produced in batches by using 3D printing technology; the obtained universal anterior mouth opener can effectively shorten the number and time of patient visits, and can be used as a radiotherapy support for oral and maxillofacial radiotherapy As well as an oral fixation device during intraoral surgery, it has great application prospects in the medical field.

The present application provides a transverse stapler for intraluminal surgery, comprising a control member, a clamping push rod assembly, a positioning needle push rod assembly, a positioning needle driving assembly and a clamping driving assembly, and the positioning needle push rod assembly is sleeved on the clamp Holding the outside of the push rod assembly, the positioning needle push rod assembly and the positioning needle drive assembly are rotatably connected, and the positioning needle push rod assembly and the positioning needle drive assembly are axially relatively fixed and rotate relative to each other, clamping the push rod assembly and the clamp The holding and driving assembly is connected in rotation, and the axial direction between the clamping push rod assembly and the clamping driving assembly is relatively fixed and the two rotate relative to each other, and the control member drives the clamping push rod assembly to rotate to make the clamping member rotate relative to the clamping driving assembly, And the control member drives the positioning needle push rod assembly to rotate through the clamping push rod assembly, so that the positioning needle rotates relative to the positioning needle driving assembly. The steering of the end of the stapler is driven by the rotating control member, which is convenient for the operator to control the steering of the end without the hand-held handle part being rotated, and is convenient to use.

The present application provides a transverse endoluminal stapler with a compact structure, including an end effector, a connecting outer tube, and a driving assembly at least partially arranged in the connecting outer tube. The assembly includes a drive housing for driving the staple cartridge housing; the staple cartridge housing is arranged in the staple cartridge accommodating chamber of the drive housing, and the staple cartridge accommodating chamber is provided with an opening for the staple cartridge housing to be connected to the central axis of the outer tube.
