Abstract

The utility model discloses a pistol hemorrhoid ligation device, relating to medical instruments. The utility model is composed of a ligation part and a suction part. The utility model is characterized in that the anus pushing inner tube of the ligation part is fixedly linked with the anus pushing outer tube of a trigger and is matched with the anus pushing outer tube in the way of clearance fit. An inner anus pushing joint and an outer anus pushing joint which are adjacent to one end of the ligation and are mutually matched in the way of clearance fit are respectively fixedly connected with the anus pushing inner tube and the anus pushing outer tube by screw threads. The utility model has the advantage of simple structure, less pain of patients during ligaturing, no edema after operation and unnecessary hospitalization.

Description

Hemorrhoid ligator

This utility model relates to medical apparatus and instruments.

In clinical position, the blood stasis Therapeutic Method is a lot.Modus operandi very bitterly, needs after the operation to be in hospital during corrective surgery; Injection, anus meeting edema recover very slow, and the liver patient is avoided usefulness; Freezing method, the anus edema is more severe; Laser, electron therapy, expensive, the easy recurrence of equipment.

The purpose of this utility model is to provide a kind of surgical condition simple, and patient's misery is little, and operation back anus is edema not, need not the hand-held gun formula blood stasis looping and binding device of being in hospital.

This utility model is achieved in that this hand-held gun formula blood stasis looping and binding device, form by cover bundle and attraction two large divisions, cover is pricked partly to include and is pushed away pipe in the anus, it is pricked the outer tube of an end and pushes away the anus nipple near cover and connects firmly with screw thread, pushing away the anus outer tube cooperates with ligament in the ejector sleeve, pushing away the anus outer tube can be along the outer tube relative motion that pushes away pipe in the anus, at an end of pricking near cover, push away the interior pipe of anus and push away the anus outer tube along its length direction protrusion, pushing away the anus outer tube connects firmly with screw thread near overlapping the outer tube of pricking an end and pushing away the anus coupling, one end of the outer tube of the other end and trigger is connected, another movable end of trigger is installed on the fixed handle, trigger has four and plays spring, cocking, drive pushes away the anus outer tube, and pipe moves in the anus along pushing away, handle has endoporus, with the outer tube interference fit that pushes away pipe in the anus, pushing away the anus coupling all is the pipe that stepped hole is arranged with pushing away the anus nipple, the little inner diameter hole that pushes away the stepped hole of anus nipple is a screwed hole, pipe is connected in the anus with pushing away, its large diameter hole is a unthreaded hole, the outer tube that it pricks an end near cover is with the elastic tape that the bundle blood stasis is used, hold blood stasis by negative pressure, push away the anus coupling stepped hole the large diameter hole with push away the outer tube matched in clearance of anus nipple, its little inner diameter hole is a screwed hole, and pushes away the anus outer tube and connects firmly, cocking pushes away the anus coupling and pushes away the motion of anus nipple relatively.When using this looping and binding device, aim at blood stasis, cocking pushes away the anus coupling and will be enclosed within the elastic tape release that pushes away on the anus nipple, and simultaneously, under vacuum suction, the rubber snare is pricked at the blood stasis base portion.The hand-held gun formula blood stasis looping and binding device of this utility model design, simple in structure, when cover is pricked, suffer from painful less, after the operation, not edema, need not to be in hospital.

Fig. 1 is the structural representation that hand-held gun formula blood stasis is pricked device.

Below, embodiment is described in detail in conjunction with the accompanying drawings.

With reference to accompanying drawing 1: hand-held gun formula blood stasis looping and binding device is pricked part and is attracted part to form by cover.

Cover is pricked partly to include and is pushed away pipe (4) in the anus, it is a bend pipe, it is pricked the outer tube of an end and pushes away anus nipple (6) with thread connection near cover, the other end and suction pump rubber tube (not drawing among the figure) socket-connect, push away anus outer tube (3) and push away pipe 4 matched in clearance in the anus, end near the cover bundle, push away the interior pipe of anus (4) and push away anus outer tube (3) along pipe range direction protrusion, pushing away anus outer tube (3) connects firmly with screw thread near overlapping the outer tube of pricking an end and pushing away anus coupling (5), one end of the outer tube of the other end and trigger (2) is connected, another movable end of trigger (2) is installed on the handle (1), cocking (2), drive pushes away anus outer tube (3) along pushing away pipe (4) motion in the anus, handle 1 plastics are made, endoporus is arranged, with the outer tube interference fit that pushes away pipe (4) in the anus, pushing away anus coupling (5) all is the pipe that stepped hole is arranged with pushing away anus nipple (6), the little inner diameter hole that pushes away the stepped hole of anus nipple (6) is a screwed hole, pipe (4) is connected in the anus with pushing away, the large diameter hole is a unthreaded hole, hold blood stasis by negative pressure, push away the large diameter hole and the outer tube matched in clearance that pushes away anus nipple (6) of the stepped hole of anus coupling (5), little inner diameter hole is a screwed hole, with push away anus outer tube (3) and connect firmly, cocking (2) pushes away anus coupling (5) and pushes away anus nipple (6) motion relatively, in addition, push away the outer tube diameter of anus nipple (6), make the multiple diameter specification according to the blood stasis size, correspondingly, the multiple diameter specification of the outer tube matched in clearance of anus nipple (6) is also made and is pushed away in the large diameter hole that pushes away anus coupling (5).

Attracting part is prior art, and negative pressure bottle produces negative pressure.

When using this hand-held gun formula blood stasis looping and binding device, earlier elastic tape is soaked in ethanol, with mosquito forceps elastic tape is opened, pack into accompanying drawing 1 indication (7) position, hold handle (1), pressing trigger (2), suction pump produces negative pressure, pushes away anus nipple (6) when holding blood stasis, pushes away anus coupling (5) elastic tape is released, the rubber snare is pricked at the blood stasis base portion, finishes operation.

Claims (1)

1, a kind of hand-held gun formula blood stasis is pricked device, form by cover bundle and attraction two parts, it is characterized in that described cover pricks part and include and push away pipe (4) in the anus, its outer tube of pricking an end near cover connects firmly with the screw thread that pushes away anus nipple (6), with the anus outer tube (3) that pushes away of the outer tube matched in clearance that pushes away in the anus pipe (4) can be along the outer tube relative motion that pushes away pipe (4) in the anus, push away the interior pipe of anus (4) and push away anus outer tube (3) along this length of tube direction and near the end protrusion that cover is pricked, pushing away anus outer tube (3) connects firmly with screw thread near overlapping the outer tube of pricking an end and pushing away anus coupling (5), one end of the outer tube of the other end and trigger (2) is connected, another movable end of trigger (2) is installed on the fixed handle (1), trigger (2) has the trigger rebound spring, handle (1) has endoporus, just in time with the outer tube interference fit that pushes away pipe (4) in the anus, in addition, with screw thread respectively and push away in the anus pipe (4) and push away the outer tube that pushes away anus nipple (6) that anus outer tube (3) connects firmly and the interior pipe that pushes away anus coupling (5) between be matched in clearance, cocking (2) pushes away anus coupling (5) and pushes away anus nipple (6) motion relatively.
