Abstract

The utility model discloses a stay bar for a multifunctional abdominal retractor. The stay bar is characterized by consisting of a polygonal lower bar (201) matched with a bedside locking sleeve, and an upper bar (202) for splicing a rack plate universal post and a curved bar, wherein the bar body of the upper bar (202) is provided with a fan-shaped insertion hole (203) into which the curved bar is inserted; a locking screw (204) for fixing the curved bar in the fan-shaped insertion hole (203) is arranged in a direction which is vertical to the fan-shaped insertion hole (203); the end part of the upper bar (202) is provided with a blind hole (205) for splicing the universal post; and an elastic bolt (206) for axially positioning the universal post and only allowing the universal post to rotate circumferentially is arranged in a direction which is vertical to the axial lead of the blind hole (205). According to the stay bar, the positioning ways of the stay bar and the curved bar are changed fundamentally, the stay bar is prevented from becoming loose due to collision once the bedside locking sleeve is not loosened during use, the operation safety is further enhanced, and reduction in the operation risk is facilitated.

Description

The multifunctional abdomen retractor strut

Technical field

This utility model relates to a kind of medical auxiliary apparatus, use in especially a kind of abdominal operation in order to the abdominal cavity of opening is pulled open, make the visual area obtain the multifunctional abdomen retractor that fully exposes, specifically a kind of multifunctional abdomen retractor strut.

Background technology

At present, carrying out liver transplantation, lobectomy of liver is stated, operation on biliary tract, full stomach or Proximal gastrectomy art, splenectomy, the strange section stream of door art etc. adopts along in the upper abdominal surgery and abdominal part straight cut or transverse incision operation of subcostal incision, in order to obtain desirable visual area, the abdominal part of opening need to be kept the good state that retracts, people have invented various abdominal retractors to replace artificial traction for this reason, the people is freed from heavy physical work, have a better effect, the patent No. of having obtained the authorization such as the applicant is that 2009101830371 multifunctional abdomen retractor is exactly one of comparatively desirable surgery assistor tool, but in clinical the use applicant find since fixedly the strut of hook plate be cylindrical structural, thereby can drive owing to the hook plate that medical personnel run into the upper end in actual use support bar rotate and cause hook plate move or loosening, can cause the loosening decline impact of strut to retract effect and operation process when serious, because of on be necessary to be improved.

Summary of the invention

The purpose of this utility model is easily in use to rotate for existing belly retractor strut to cause hook plate displacement or loosening problem, designs a kind of multifunctional abdomen retractor strut with anti-rotating function.

The technical solution of the utility model is:

A kind of multifunctional abdomen retractor strut, it is characterized in that it is comprised of the polygon lower beam 201 that matches with the bedside lock sleeve and the upper boom 202 that is used for the universal post of plug-in mounting rack-plate and bent type bar, be provided with a blade recepatcle 203 that is used for installing bent type bar at the shaft of described upper boom 202, be equipped with for the holding screw 204 that bent type bar is fixed on blade recepatcle 203 in the direction vertical with blade recepatcle 203; The end of upper boom 202 is provided with the blind hole 205 of the universal post of plug-in mounting, is equipped be used to the resilient pin 206 that universal axis of a cylinder can only circumferentially be rotated to the location in the direction vertical with blind hole 205 axial lines.

The cross sectional shape of described lower beam 201 is regular hexagon.

Described upper boom 202 is cylindrical structural.

The lower end of described lower beam 201 is spherical structure.

The utlity model has following advantage:

This utility model has fundamentally changed the mode of strut and bent type bar location, in the use only otherwise unclamp the lock sleeve of bedside, strut can never occur because of collision occur loosening, further improved the safety of operation, be conducive to reduce operation risk.

This utility model is simple in structure, is easy to realize.

Description of drawings

Fig. 1 is perspective view of the present utility model.

The specific embodiment

Following structure drawings and Examples are further described this utility model.

As shown in Figure 1.

A kind of multifunctional abdomen retractor strut, it is comprised of the polygon lower beam 201 that matches with the bedside lock sleeve and the upper boom 202 that is used for the universal post of plug-in mounting rack-plate and bent type bar, lower beam 201 preferably adopts the regular hexagon structure, and for the ease of in the lower beam insertion lock sleeve, the end of lower beam preferably is spherical structure, upper boom can be polygonized structure, it also can be cylindrical structural, from angle attractive in appearance, the circular structure of upper boom 202 preferred design, be provided with a blade recepatcle 203 that is used for installing bent type bar at the shaft of described upper boom 202, be equipped with for the holding screw 204 that bent type bar is fixed on blade recepatcle 203 in the direction vertical with blade recepatcle 203; The end of upper boom 202 is provided with the blind hole 205 of the universal post of plug-in mounting, is equipped be used to the resilient pin 206 that universal axis of a cylinder can only circumferentially be rotated to the location in the direction vertical with blind hole 205 axial lines.

This utility model does not relate to the part prior art that maybe can adopt same as the prior art to be realized.
