DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the utility model embodiment clearer, the technical scheme in the embodiment will be clearly and completely described below in conjunction with the drawings in the utility model embodiment, and the following embodiments are used to illustrate the utility model.

[0026] As Figs. 1 to 4 shown, a double-channel endoscope protective sleeve, comprising an endoscope 1, a protective sleeve 2 sleeved outside the endoscope 1, a protection fixed mechanism 31 provided on the protective sleeve 2, an auxiliary protection mechanism 32 provided on one side of the protection fixed mechanism 31, the protection fixed mechanism 31 comprising a connecting sleeve 311 fixedly connected to the outer wall of the protective sleeve 2, a screw thread 312 provided on the outer wall of the connecting sleeve 311 away from the protective sleeve 2, a through slot provided on the outer wall of the connecting sleeve 311, an elastic piece 313 fixedly connected to the inner wall of the through slot, a stress block 314 fixedly connected to the top end of the elastic piece 313, an extrusion block 315 fixedly connected to the bottom end of the elastic piece 313, a threaded sleeve 316 threadedly connected to the screw thread 312, a liquid suction pipe 317 provided in communication through the connecting sleeve 311 and the protective sleeve 2, a liquid suction channel 318 provided in communication on the outer wall of one end of the liquid suction pipe 317, the liquid suction channel 318 fixedly connected to the inside of the protective sleeve 2 in penetration, and an operating handle 319 fixedly connected to the bottom end of the connecting sleeve 311.

[0027] Further, the number of elastic pieces 313 and extrusion blocks 315 is four respectively, and the elastic pieces 313 and extrusion blocks 315 are evenly and equidistantly distributed on the outer wall of the connecting sleeve 311, so that the upper, lower, left and right four sides of the endoscope 1 can be uniformly clamped and limited, and the stability of the endoscope 1 installation is ensured.

[0028] Further, the elastic member 313 is made of elastic rubber or elastic plastic, so that the elastic member 313 can have elastic effect, and when the elastic member 313 is not extruded by the inner wall of the threaded sleeve 316, the elastic member 313 can reset to drive the extrusion block 315 not to contact the outer wall of the endoscope 1, so as to ensure the convenience of the endoscope 1 installation.

[0029] Further, the stress block 314 is in the shape of a slope, and the top end of the stress block 314 is provided with a slope setting, which is in the state of being high on the left and low on the right. When the threaded sleeve 316 is threadedly moved, the inner wall of the threaded sleeve 316 can extrude the slope setting, so as to push the extrusion block 315 to move, thereby forming the extrusion limiting effect on the outer wall of the endoscope 1.

[0030] The auxiliary protection mechanism 32 comprises a slot 321 provided on the outer wall of one end of the protection sleeve 2, and a clamping groove 322 is provided at the bottom end of the inner wall of the slot 321. The clamping groove 322 is provided with a clamping block 323, and the clamping block 323 is fixedly connected with a lens cover 324 on one side of the outer wall. The lens cover 324 is provided with an extrusion sleeve 325 on one end of the outer wall.

[0031] Further, the number of clamping blocks 323 is two, and the clamping blocks 323 are symmetrically arranged on the outer wall of the lens cover 324. The outer wall of the clamping block 323 is slightly larger than the inner wall of the clamping groove 322. In this way, when the clamping block 323 is clamped in the clamping groove 322, the clamping groove 322 can clamp the clamping block 323, so as to improve the installation stability of the lens cover 324.

[0032] Further, the material of the protection sleeve 2 and the lens cover 324 is transparent flexible material, and the diameter of the lens cover 324 is slightly larger than the inner diameter of the protection sleeve 2. In this way, when the lens cover 324 is clamped in the protection sleeve 2, the tension of the protection sleeve can press the outer wall of the lens cover 324, so as to fix the lens cover 324.

[0033] The implementation principle of the double-channel endoscope protective sleeve of the embodiment is as follows: first, the threaded sleeve 316 is screwed on the connecting sleeve 311 through the threads 312 on the outer wall of one end of the connecting sleeve 311, then the forward screwing is stopped, so that the inner wall of the threaded sleeve 316 does not contact the force receiving block 314, and the threaded sleeve 316 is in a connected state with the connecting sleeve 311, then the endoscope 1 is inserted into the threaded sleeve 316 through the through hole in one end of the threaded sleeve 316, so that the endoscope 1 passes through the threaded sleeve 316, the connecting sleeve 311 and the protective sleeve 2, and the endoscope 1 is inside the protective sleeve 2, so that the endoscope 1 is protected, after the sleeve is inserted, the threaded sleeve 316 can be continuously rotated inward, at this time the threaded sleeve 316 will move to the left, and in the movement process of the threaded sleeve 316, the inner wall thereof will contact and extrude the force receiving block 314, the force receiving block 314 subjected to extrusion will generate an inward moving force, at this time the force receiving block 314 will press the elastic member 313, so that the elastic member 313 deforms inwardly, so that the elastic member 313 drives the extrusion block 315 on the outer wall of one end to move inwardly, at this time the extrusion block 315 will move and then contact and extrude the outer wall of the endoscope 1, so that the extrusion blocks 315 on the four sides can extrude and limit the endoscope 1, so as to complete the fixed connection between the endoscope 1 and the protective sleeve 2, and ensure that the endoscope 1 does not relatively displace in the protection of the protective sleeve 2, so as to ensure the safety of the operation, when it is necessary to extract the excess fluid in the patient's body, first connect the liquid extraction pipe 317 with the external liquid extraction equipment, then the liquid extraction channel 318 can be used to extract the fluid in the patient's body, so as to further improve the accuracy and safety of the operation.

[0034] After the endoscope 1 is inserted and placed, the lens cover 324 can be installed, in the installation process, first align the extrusion sleeve 325 on one end of the lens cover 324 with the opening at one end of the protective sleeve 2, then insert the extrusion sleeve 325 on one end into the protective sleeve 2 through the tapered surface, while ensuring that the clamping block 323 is inserted and clamped in the insertion slot 321, with the movement of the lens cover 324 being pushed inwardly, at this time the tapered surface of the extrusion sleeve 325 will extrude and expand the inner wall of the protective sleeve 2, after the protective sleeve 2 is expanded, the outer wall of the lens cover 324 can be inserted into the inner wall of the protective sleeve 2, in the process of insertion, the clamping block 323 will be moved to the bottom end of the inner wall of the insertion slot 321, then rotate the lens cover 324 counterclockwise to rotate the clamping block 323, then clamp the clamping block 323 in the clamping groove 322, so as to complete the clamping installation of the lens cover 324, the lens cover 324 can seal and cover the protective sleeve 2, so as to protect the endoscope 1.
