Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1-4, a lithotomy device for hepatobiliary surgery includes:
the stone taking part 1 comprises an air pump 10, an adjusting bolt 11, a hollow sleeve 12, an air duct 13 and a stone taking assembly 14;
one end of the air duct 13 is fixedly connected with the air pump 10, the other end of the air duct passes through the hollow sleeve 12 and is fixedly connected with the calculus removing assembly 14, and the adjusting bolt 11 is fixedly connected with the hollow sleeve 12;
the top end of the collecting cylinder 2 is uncovered, a partition plate 22 for dividing the collecting cylinder 2 into a working cavity 20 and a collecting cavity 21 is arranged in the collecting cylinder, and the adjusting bolt 11 is movably connected to the bottom wall of the working cavity 20;
before the use, firstly, the air pump 10 inflates the upper air bag 1401 and the lower air bag 1402 to check whether the air duct 13 is bent or blocked, and simultaneously, the tensile tape 141 in the tensile tape box 142 is checked whether to work normally, if no problem exists, the air pump 10 discharges air, so that the air bag 140 is fixed by the tensile tape 141 and is in a contraction state.
When the calculus removing device is used specifically, firstly, the adjusting bolt 11 is rotated under the assistance of the micro camera 132, the rotation of the outer tube 120 is driven by the rotation of the adjusting bolt 11, because the clamping groove 1210 on the inner tube 121 is mutually embedded with the clamping block 201 arranged on the cavity wall of the working cavity 20, the inner tube 121 cannot rotate along with the outer tube 120, under the action of threaded connection, the inner tube 121 can move up and down along with the rotation of the outer tube 120, the actual using length of the hollow sleeve 12 is adjusted to drive the calculus removing component to move, when the calculus removing component is moved to the position of the calculus, the calculus position is ensured to be in the position between the upper air bag 1401 and the lower air bag 1402, then, the air is inflated through the air pump 10, because the one-way valve 131 arranged at the air duct 13 and the upper air bag 1401 is a one-way air inlet valve, and the one-way valve 131 arranged at the lower air bag 1402 is a one-way air outlet valve, the, the calculus collecting device is characterized in that the calculus collecting device can gradually contact with the calculus in the expansion process, the shape of the contact surface of the calculus collecting device can be changed according to the shape and the size of the calculus, after the calculus is fixed by the air bag 140, the adjusting bolt 11 is adjusted to slowly drag the calculus collecting assembly 14 and the calculus collected into the collecting cylinder 2, the expanded air bag 140 is just arranged in the collecting cavity 21, air is exhausted through the air pump 10, due to the one-way exhaust valve, the lower air bag 1402 can exhaust air preferentially, the calculus falls into the collecting cavity 21 under the action of gravity, and touches the fan-shaped safety piece 211 in the falling process, due to the hinge connection, the calculus can knock the fan-shaped safety piece 211 to fall to the bottom of the collecting cavity, then the fan-shaped safety piece 211 returns to the initial position under the action of the elastic hinge, the phenomenon that the calculus rolls out from the collecting cavity under the unexpected situation is avoided, and then, due to the fact that the stretching belt 141 retracts, the air bag 140 can exhaust air, and the next stone can be taken.
Specifically, the stone removing assembly 14 comprises two groups of air bags 140, a stretching belt 141 and a stretching belt box 142;
the two ends of the stretching strap 141 are movably connected in the stretching strap box 142, the middle position of the stretching strap 141 is fixedly connected to the right end of the air bag 140, the stretching strap box 142 is fixedly connected to the upper end of the air duct 13, the arrangement of the stretching strap 141 can control the expansion of the air bag 140 in the horizontal direction in the expansion process, and the air bag 140 can be fixed for the next use by assisting the air exhaust through the self retraction during the air exhaust.
Specifically, the air bag 140 comprises an upper air bag 1401, a lower air bag 1402 and an air pipe 1403, wherein the upper air bag 1401 is inverted to be in a convex shape, the lower air bag 1402 is in a convex shape, and two ends of the air pipe 1403 are respectively and fixedly connected with the upper air bag 1401 and the lower air bag 1402; after the upper air bag 1401 and the lower air bag 1402 are expanded, the calculi can be clamped, and the calculi with different sizes and shapes can be clamped due to the strong deformation capacity of the air bag 140.
Specifically, the upper end of the airway tube 13 is fixedly connected with the upper air bag 1401 and the lower air bag 1402 respectively, and the joint of the airway tube and the lower air bag is provided with a one-way valve 131; the one-way valve 131 arranged at the positions of the air duct 13 and the upper air bag 1401 is a one-way air inlet valve, so that the upper air bag 1401 is preferentially expanded during inflation, the calculus is prevented from being squeezed away by the lower air bag 1402, the one-way valve 131 arranged at the connecting position of the air duct 13 and the lower air bag 1402 is a one-way exhaust valve, and therefore when the calculus is placed by the air bag 14, the lower air bag 1402 preferentially exhausts air, and the calculus is convenient to fall.
Specifically, the hollow sleeve 12 comprises an outer tube 120 and an inner tube 121, the outer tube 120 is in threaded connection with the inner tube 121, and a trapezoidal clamping groove 1210 is formed in the outer wall of the inner tube 121; the hollow sleeve 12 is arranged so that the airway tube 13 can pass through it to connect with the calculus removal assembly 14, and the position of the calculus removal assembly 14 can be adjusted and controlled by the arrangement of the sleeve.
Specifically, a positioning fixture block 201 matched with the trapezoidal fixture groove 1210 is arranged on the inner wall of the working cavity 20; the positioning fixture block 201 is matched with the body shape clamping groove 1210 to control the inner tube 121, so that the inner tube 121 can only move up and down and can not rotate along with the rotation of the outer tube 120.
Specifically, a strip-shaped transparent observation window 210 is arranged on the outer wall of the collection cavity 21, and a fan-shaped safety piece 211 connected with a one-way spring hinge of the collection cavity is arranged at the upper end of the inner wall of the collection cavity; the transparent observation window 210 is arranged to enable each calculus to fall and be seen, one is to confirm that the calculus is really taken out, the other is to prevent the collection cavity 21 from being filled with the calculus to influence the overall use through the observation of the transparent observation window 210, and the fan-shaped safety piece 211 is arranged to prevent the calculus from falling into the collection cavity 21 and then rolling out of the collection cavity 21 under the accidental condition.
Specifically, the upper end of the airway tube 13 is movably connected with a micro-camera 132, and the micro-camera 132 is located between the upper air bag 1401 and the lower air bag 1402; the micro-camera 132 is an indispensable device since medical personnel cannot observe with the naked eye the area where the stone is located.
The present invention has been further described with reference to the embodiments, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
