Technical Field

The utility model relates to the field of medical equipment, specifically a uterus draw gear is used in gynaecology's uterus resection entirely.

Background

Hysterectomy is divided into various surgical procedures such as partial resection, sub-total resection, sub-extensive resection and extensive resection. For patients with local infection, tissue necrosis, and uterine edema and thickening, a total cutting of uterus is mostly adopted. Traction devices are needed in any hysterectomy operation, but common traction devices such as traction forceps, uterine dragging cups and the like realize 'grabbing' action by squeezing rigid bodies and uterine tissues, perform traction action on the premise of the action, and belong to a hard traction mode. However, with the popularization of hysterectomy, the defects of the hard traction mode of traction forceps and uterine dragging cups are gradually reflected, and especially in the full-section hysterectomy, the friction force is reduced because blood, pus and other liquid are adhered to the surface of the tissue, so that greater pressure is needed for 'grabbing' action, and great damage is caused to the uterine tissue.

Detailed Description

According to the above structural features of the present application, the embodiments of the present application will be further explained:

referring to fig. 1-7, the embodiment provides a uterus traction device for gynecological hysterectomy, which comprises a shell 1, wherein the shell 1 is of a rod-shaped shell structure.

Two rows of sucker through holes 12 are longitudinally formed in the left shell at the upper part of the shell 1, and a miniature sucker 2 is clamped and mounted in each sucker through hole 12 in an interference fit annular manner; the inner cavity of the miniature sucker 2 is communicated with the inner cavity of the shell 1.

A sliding groove 11 structure is longitudinally arranged on the left shell at the lower part of the shell 1, and the sliding groove 11 is communicated with the inner cavity of the shell 1; the left side of the inner cavity of the shell 1 is provided with a baffle 3, the upper part of the baffle 3 is blocked at the inner side of the sucker through hole 12, the lower part of the baffle 3 is provided with a sliding key 31, the sliding key 31 is positioned in the sliding groove 11, and the sliding key 31 can slide up and down in the sliding groove 11.

A plurality of fixing devices 4 are arranged between the right side surface of the baffle 3 and the right side surface of the inner cavity of the shell 1, and the fixing devices 4 and the sucker through holes 12 are positioned at the same height; the fixing device 4 comprises a push plate 41, a fixing clamping plate 42 and a pressure spring 43; the fixing clamping plate 42 comprises an upper clamping plate 421 and a lower clamping plate 422, and the upper clamping plate 421 and the lower clamping plate 422 are fastened through self-tapping screws; the right end of the fixed splint 42 is fastened with the right surface of the inner cavity of the shell 1 through a tapping screw; the push plate 41 is positioned between the upper clamping plate 421 and the lower clamping plate 422 and is in clearance fit, and the top end of the push plate 41 is wedge-shaped, so that the baffle 3 can be pushed up again without being clamped when sliding excessively downwards, and the adjustment fault tolerance rate is increased; and the push plate 41 is provided with an air hole 411; the right side of the push plate 41 is connected with a compression spring 43, and the compression spring 43 is positioned between the upper clamping plate 421 and the lower clamping plate 422. Under the thrust of the pressure spring 43, the top end of the push plate 41 compresses the baffle 3, and the baffle 3 compresses the left side wall of the inner cavity of the shell 1, so that the sucker through hole 12 is effectively blocked.

A sealing plate 5 is arranged in the inner cavity of the shell 1 through a tapping screw, and the sealing plate 5 is positioned on the inner side of the sliding groove 11; the sealing strip is arranged on the left side face of the top end of the sealing plate 5 and is positioned between the sealing plate 5 and the baffle 3 to prevent the air leakage of the sliding chute 11.

The bottom of the inner cavity of the shell 1 is connected with a hose 6 through an air hole, the other end of the hose 6 is connected with an air pump, and the air pump is an air pump.

The miniature sucker 2 is made of rubber materials, and compared with rigid materials such as metal, hard plastic and the like, the rubber materials are soft, so that the collision damage to uterine tissues can be effectively reduced; meanwhile, the miniature sucking disc 2 made of rubber materials and the sucking disc through hole 12 have better sealing performance after being installed.

The baffle 3 and the sliding key 31 are connected in a self-tapping screw fastening mode or an integrated injection molding mode.

The working principle is as follows:

push down feather key 31 along 1 direction in spout, drive baffle 3 and move down, originally by the opening in proper order of the sucking disc through-hole 12 of shutoff from the top down, select the sucking disc through-hole 12 quantity of opening according to the size of actual uterus tissue, if: the area of the uterine tissue is 4 square centimeters, 2 columns, 2 rows and =4 sucker through holes 12 are selected to be exposed, namely 4 micro suckers 2 can work normally; the area of the uterine tissue is 6 square centimeters, 2 columns × 3 rows =6 sucker through holes 12 are selected to be exposed, and 6 micro suckers 2 can work normally. The air pump reduces the air pressure in the inner cavity of the shell 1 through the hose 6, and the miniature sucker 2 with the normally working top end sucks the surface of the uterine tissue tightly to realize the 'grabbing' action; then the tail end of the shell 1 is swung, and the uterine tissue moves along with the top micro sucker 2 to realize traction. Because the surface of the womb tissue with pathological changes is adhered with blood, purulent water and other liquids during operation, the friction force can be reduced, and therefore, the firm grabbing action can be realized only after the blood, the purulent water and other liquids are pressed into the inner cavity of the shell 1 by air pressure.

To sum up, to the technical personnel in the field, according to the guidance of the utility model, under the prerequisite that does not deviate from the principle and spirit of the utility model, to the change, modification, replacement, deformation that the utility model was done still fall into the protection scope of the utility model.
