Abstract

The utility model provides an auxiliary space expander, which comprises an inflating handle, an air inlet, a first air outlet and a second air outlet, wherein the air inlet is used for the inflating handle to enter air; the inflating handle is provided with an exhaust end which is connected with a connecting pipe, an air bag is arranged at the end part of the connecting pipe, which is far away from the inflating handle, and the inflating handle can be pinched to inflate and expand the air bag; the connecting pipe is provided with an exhaust port, and a plug used for controlling the air bag to exhaust is installed on the exhaust port. Effectively avoids the problems that the existing space expanding tool which is manufactured by connecting the disposable abdominal cavity drainage tube or catheter with the surgical sterile glove or finger stall is complicated to manufacture, and the pipeline is bound to cause slow expansion or emptying. Moreover, during the expanding process, the bundled surgical sterile gloves or finger sleeves often burst or separate from the tube body, which easily causes the glove fragments to remain in the patient body, which affects the operation efficiency and reduces the operation safety.

Description

Auxiliary space expander

Technical Field

The utility model relates to the field of medical equipment, specific supplementary space expander that says so.

Background

The laparoscope is similar to gastroscope and colonoscope, is a medical instrument with a light source and a miniature camera, and belongs to the class III medical instruments. Before laparoscopic surgery is performed, a good spatial view is required to complete the surgical operation safely and efficiently. Unlike conventional laparoscopic surgery, posterior abdominal access (or extraperitoneal access) such as urology does not have the inherent advantage of abdominal space, and requires temporary construction of an operating space prior to laparoscopic surgery.

When a laparoscopic surgery space is established in urinary surgery, objects are taken on the spot, a disposable abdominal cavity drainage tube or a catheter is utilized, a surgical sterile glove or a finger sleeve is bound at the front end of the surgical sterile glove or the finger sleeve through silk threads, and the surgical space is expanded by filling water into the tube to realize the filling of the glove or the finger sleeve. The expansion tool is cumbersome to make and the tubing is tied up resulting in slow expansion or emptying. Moreover, in the expanding process, the bound surgical sterile gloves or finger sleeves are often burst or separated from the tube body, so that the glove fragments are even remained in the body of a patient, the operation efficiency is further influenced, and the operation safety is reduced.

Therefore, it is desirable to provide an auxiliary space expander to solve the above problems, which is needed for the current urology surgery to create a laparoscopic surgical space.

Detailed Description

The above-described scheme is further illustrated below with reference to specific examples. It should be understood that these examples are for illustrating the present invention and are not intended to limit the scope of the present invention. The conditions used in the examples may be further adjusted according to the conditions of the particular manufacturer, and the conditions not specified are generally the conditions in routine experiments.

In a particular embodiment, an auxiliary space expander is provided, comprising an inflatable handle 1 and an air inlet 1.1 provided for the inflatable handle 1 to enter air; the inflating handle 1 is provided with an exhaust end which can be connected with the connecting pipe 2, the end part of the connecting pipe 2, which is far away from the inflating handle 1, is provided with an airbag 3 which can be inflated and expanded, and the inflating handle 1 is pinched to enable airflow to flow into the airbag 3 so as to inflate and expand the airbag;

the connection tube 2 is provided with an exhaust port 4 through which an air flow can be exhausted from the airbag 3, and a plug 4.1 for controlling the exhaust of the airbag 3 is attached to the exhaust port 4.

In combination with the scheme, when the device is actually used, firstly, a small 2cm incision is made at a position to be operated, the bending forceps stretch the subcutaneous and muscle layers and then enter the posterior abdominal cavity or the extraperitoneal cavity, then the forefinger is used for firstly stretching into the incision to perform intermittent peeling and expansion, then the air bag 3 is placed into the incision, the air exhaust hole 4 is blocked by the plug 4.1, the air flow flows from the connecting pipe 2 to the inside of the air bag 3 by pinching the inflating handle 1, the air inlet 1.1 can enable the inflating handle 1 to suck in external air after pinching once, so that new air is formed in the inflating handle, the air is repeatedly pinched to perform continuous inflation, and the inflation quantity is determined according to the requirements of a patient.

After the expansion request is reached, the plug 4.1 is opened to allow the gas to escape through the vent hole 4, and finally the airbag 3 is taken out to complete the expansion.

In summary, in order to enable the doctor to perform the inflation or deflation operation with one hand, the exhaust port 4 is provided at one end of the connection tube 2 close to the inflation handle 1. Thereby improving the convenience of doctors.

In addition, in order to improve the convenience of the doctor in inflation and exhaust, the plug 4.1 comprises a spherical shell 4.12, and a hole 4.121 communicated with the through hole 4.11 at the end part of the plug 4.1 is formed in the side wall of the spherical shell 4.12;

an elastic tube which can be communicated with the connecting tube 2 is arranged at the exhaust port 4; the spherical shell 4.12 can be inserted into the elastic tube in a sealing manner and can extend into the connecting tube 2, so that the hole 4.121 is communicated with the connecting tube 2.

In combination with the above, when in use, the doctor can exhaust the air by inserting the spherical shell 4.12 into the connecting tube 2 to connect the hole 4.121 with the connecting tube 2. On the other hand, when the spherical shell 4.12 is pulled out of the connection tube 2 and the handle 1 is connected to the connection tube 2 and the airbag 3, the handle 1 is pinched to flow the air into the airbag 3, thereby expanding the airbag.

The elastic tube has the same inner diameter as the connection tube 2 so that the spherical shell 4.12 can be inserted into and removed from the connection tube 2 in a sealed manner. And the spherical shell 4.12 can rotate in the connecting pipe 2 to change the direction of the hole 4.121, so that the hole 4.121 is communicated with the connecting pipe 2.

In addition, in order to avoid the influence on the expansion effect caused by the fact that the surface of the air bag 3 slides in the patient due to smoothness of the surface of the air bag after being inflated and expanded, a plurality of salient points are arranged along the outer wall of the air bag 3, and then the friction force between the air bag 3 and the dirty organs can be increased.

In addition, the balloon 3 is provided on the side wall of the connection tube 2 in order to further improve the expansion effect. The balloon 3 can be expanded to both sides when expanded, and the arrangement of the balloon 3 at both sides can facilitate the introduction of the connecting tube 2 into the incision.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
