Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-2, a hip joint combination exposure device comprises a hip joint opening mechanism and a positioning frame mechanism; the hip joint opening mechanism comprises a support ring 1 which is horizontally arranged; a bearing sleeve 2 is rotatably sleeved outside the support ring 1; a set screw 3 is arranged on the bearing sleeve 2; expanding components are distributed on the support ring 1 along the circumferential direction; the expanding and supporting assembly comprises a support 4 fixed on the inner side of the support ring 1; a sleeve 5 is vertically arranged in the support 4; two sides of the lower part of the sleeve 5 are respectively and correspondingly and rotatably connected with two sides of the support 4; a screw 6 is sleeved in the sleeve 5; a guide strip 7 is vertically fixed in the sleeve 5; a guide groove 8 is formed on the screw 6; the guide groove 8 slides corresponding to the guide strip 7; the upper end of the sleeve 5 is coaxially and rotatably connected with an adjusting threaded sleeve 9; the adjusting screw sleeve 9 is in threaded connection with the screw 6; the lower end of the screw 6 is fixed with an expanding hook 10; the upper end of the support ring 1 is provided with a stop block 11; the stop block 11 is connected with the upper part of the sleeve 5 through a spring 12;

the positioning frame mechanism comprises a support rod 13 arranged along the left-right direction; a right buckle frame 14 is fixed at the right end of the supporting rod 13, and a left buckle frame 15 is sleeved on the left side of the supporting rod 13 in a sliding manner; a vertical rod 16 is fixed on the upper side of the left end of the supporting rod 13; an extension rod 17 is fixed on the right side of the upper end of the vertical rod 16; the left side of the outer wall of the bearing sleeve 2 is fixed with the right end of the extension rod 17; a hole seat 18 is fixed at the left end of the supporting rod 13; the hole seat 18 is connected with a fastening bolt 19 in a threaded manner; the fastening bolt 19 penetrates the vertical rod 16 in the left-right direction; the right end of the fastening bolt 19 is rotatably connected with the left end of the left buckle frame 15.

The upper end of the support ring 1 is distributed with a sleeve shell 20 along the circumferential direction; a sliding cavity 21 is arranged at the inner side of the shell 20; the stop blocks 11 and the sliding cavities 21 slide correspondingly one to one; the outer end of the casing 20 is in threaded through connection with an adjusting bolt 22; the inner end of the adjusting bolt 22 is rotatably connected with the stop block 11; the vertical rod 16 is a telescopic positioning rod structure.

Firstly, a supporting rod 13 is arranged at the lower side of an operating table, a fastening bolt 19 is screwed, so that a left buckling frame 15 moves along the supporting rod 13, and finally the device is buckled with the operating table through the left buckling frame 15 and a right buckling frame 14, so that the device is fixed with the operating table; subsequently, the hip distraction mechanism is moved to the appropriate height by adjusting the height of the vertical rod 16 itself.

When the surgical field at the hip joint is expanded, firstly, the support ring 1 rotates along the bearing sleeve 2 to adjust the circumferential position of the expansion assembly, so that the expansion assembly is adapted to the position of the surgical opening to be expanded; then, screwing the adjusting screw sleeves 9 at all positions, and respectively adjusting the expanding hooks 10 to proper height positions (ensuring that the expanding hooks 10 can reach the operation opening); afterwards, stir screw 6 upside, compress spring 12, make expand and prop hook 10 and incline to the inboard, wait to expand when propping the muscle that hook 10 hooked art mouth one side, remove the external force to screw 6, with the help of the resilience force of spring 12, expand and prop hook 10 and can be outwards promoted to expand the art mouth and prop.

When the expanding hook 10 expands the operation opening, the stopper 11 can slide in the sliding cavity 21 by screwing the adjusting bolt 22. When the stop block 11 approaches the sleeve 5, the compressed amplitude of the spring 12 is increased, the elastic thrust on the sleeve 5 is increased, and the expanding amplitude of the expanding hook 10 is increased; when the stop 11 is far away from the sleeve 5, the compressed amplitude of the spring 12 is reduced, the elastic thrust on the sleeve 5 is reduced, and the expanding amplitude of the expanding hook 10 is reduced. Through the operation, the degree of the expanding hook 10 expanding the operation opening can be changed, and the applicability is enhanced.

In addition, among this technical scheme, because realize expanding to art mouth department muscle with the help of the thrust of spring 12 and prop, so expand and prop 10 departments of supporting still have the room of elastic buffer when expanding to prop, for example expand prop after the time is longer, accessible toggle screw 6, appropriately relax expand prop the hook 10 expand prop the pressure to the expanding of art mouth department to improve the blood circulation of art mouth muscle, effectively reduce the damage that causes the muscle, be favorable to the recovery of postoperative.
