Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an anti-rotation expansion device for intestinal surgery. Background Art

[0002] Currently, during intestinal surgery or testing, equipment generally needs to be introduced through the human intestine. Due to the peristalsis of the intestine, the inner and outer diameters of the intestine will change differently during the entry process. Therefore, there is an urgent need for an expander that can adapt to the changes in the inner diameter of the intestine and prevent rotational expansion of the knot to facilitate surgical operations. Utility Model Content

[0003] The utility model aims to provide an anti-rotation expansion device for intestinal surgery, which adopts an expansion traction hook to prevent the peristalsis and rotation of the intestine, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-rotation and expansion device for intestinal surgery, comprising at least one support plate; a bayonet, which is opened at the outer edge of the support plate and is inclined as a whole; a silicone strip, which is inserted into the bayonet to complete the installation, and a retractor is fixed at one end of the silicone strip, and the retractor can be used to pull the intestine during the operation.

[0005] Preferably, connecting grooves are symmetrically provided at both ends of the support plates, fixing bolts are passed through the connecting grooves, and locking nuts are screwed into the threaded portions of the fixing bolts. Through this connection method, a stable connection between every two adjacent support plates is achieved, and the fit between the support plates and the human body can be adjusted according to actual needs by changing the connection position in the connecting grooves.

[0006] Preferably, the end of the retractor is also covered with a rubber sleeve, the inner diameter of the rubber sleeve is equal to the outer diameter of the retractor, and during use, a flexible connection can be made through the rubber sleeve to avoid direct contact with the intestine and cause damage.

[0007] Preferably, the support plate is arc-shaped as a whole, and at least three support plates are connected end to end to form an annular structure.

[0008] Preferably, one end of the silicone strip bulges outward, and the width of the bulge and the silicone strip are both greater than the inner width of the bayonet. During installation, the silicone strip can be squeezed through the bayonet to achieve a stable installation. At the same time, the bulging area on the side of one end of the silicone strip can be used for blocking and protection, further avoiding the risk of falling off.

[0009] Preferably, the opening of the bayonet is rounded, and the length inside the bayonet is greater than the width of the silicone strip, so that multiple silicone strips can be inserted. In actual use, adjustments can be made according to surgical requirements.

[0010] Preferably, the outer diameter of the rubber sleeve is smaller than the width of the silicone strip to avoid protrusion that affects normal use, and the length of the rubber sleeve is equal to the length of the hook.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In the utility model, the support plate can provide silicone strips and retractors for stable installation and placement. At the same time, by adjusting the fixing bolts, the bending angle of the support plate can be flexibly changed to better fit the physiological curvature of the surgical site, and the placement of the support plate is more stable and reliable; the bayonet can better stabilize the silicone strip, ensuring that it is not easy to slide even with greater pulling force. Multiple silicone strips can be placed on one bayonet at the same time, and the retractor can ensure that the traction will not slip or break during the operation. The traction strength and angle can be adjusted at any time to meet the clinical traction and fixation needs. BRIEF DESCRIPTION OF THE DRAWINGS
