Description

Gallbladder puncture-bile exchange device

Technical Field

The invention relates to the field of medical instruments, in particular to a gall bladder puncture-bile exchange device.

Background

The gallbladder-protecting and calculus-removing operation is to remove calculus on the basis of preserving gallbladder, and mainly aims at the diseases of gallbladder calculus. The gallbladder-protecting calculus-removing operation can not only avoid complications caused by cholecystectomy, but also meet the gallbladder-protecting requirements of patients, and no serious complications and death cases exist so far, so that the gallbladder-protecting calculus-removing operation is a humanized treatment means for patients with partial good gallbladder functions and strong gallbladder-protecting willingness.

In the stone operation is got to gall-bladder, when cutting open the gall-bladder in the twinkling of an eye, the bile gushes out, cause pure thick bile to flow into the abdominal cavity, though it often adopts timely attraction of scope clinically, and carry out abundant washing to the abdominal cavity after the operation is accomplished, in order to reduce the absorption of peritoneum to the bile, reduce postoperative biliary peritonitis, the degree of abdominal pain, no matter how timely that the scope attracts in the twinkling of an eye is cut to the gall-bladder, how abundant postoperative peritoneal irrigation, always have more or less bile pollution abdominal cavity, by the peritoneal absorption, arouse biliary peritonitis, thereby lead to the patient to appear the abdominal pain, generate heat even, the shivering. Increase patient's postoperative uncomfortable and feel, reduce the patient and protect the courage to get the acceptance of stone under the scope, bile peritonitis can prolong the time of being in hospital in addition, increases the cost of being in hospital.

Detailed Description

The technical solution of the present invention is further described below with reference to the accompanying drawings and examples.

In the description of the present invention, the terms "head end" and "front end" are the ends that are remote from the operator. The positional or orientational relationships indicated in the present invention are for convenience of description and simplicity of description only and thus should not be construed as limitations of the present invention.

In the gallbladder calculus removing operation, bile gushes out at the moment of cutting the gallbladder, so that more or less bile always pollutes the abdominal cavity and is absorbed by the peritoneum to cause biliary peritonitis, and consequently, abdominal pain, even fever and shivering of a patient occur. Based on the above, the apparatus of the present invention was designed.

Fig. 1 is a schematic structural diagram of a gallbladder puncturing-bile exchanging device according to the present invention, which includes: the device comprises an inner core 1, a puncture needle 2 connected with the head end of the inner core 1, a transfusion cavity 3 communicated with the inner core 1, a sacculus 4 which is coated on the outer side of the front end of the inner core 1 and penetrates into a gall bladder along with the puncture needle 2 in a use state, and an air injection cavity 5 communicated with the sacculus 4.

The transfusion cavity 3 is used for transfusion to the gall bladder through the inner core 1 and the puncture needle 2 and is used for bile exchange. The transfusion cavity 3 can be connected with a two-way, and after sucking bile, normal saline is transfused to the gall bladder.

The sacculus 4 is made of elastic materials and is tightly wrapped on the outer side of the front end of the inner core 1, and the sacculus easily enters the gallbladder along with the puncture needle 2 after the puncture needle 2 punctures the gallbladder. The inner core 1 may be provided with an air injection hole for injecting air into the balloon 4 at a position corresponding to the balloon 4. In some embodiments, the inner core 1 is provided with a gas injection pipeline connected with a gas injection hole inside, and the gas injection cavity 5 on the outer side of the inner core 1 is connected with the gas injection pipeline, so as to allow the gas injection cavity 5 to inject gas into the balloon 4. The balloon 4 may be inflated by injecting a liquid into the balloon 4. The gas injection cavity 5 can be connected with a connector and then connected with a two-way connector for controlling the gas injection amount and adjusting the size of the gas bag. After the saccule 4 enters the gallbladder, air is injected to expand the saccule 4, so that a puncture hole is blocked, bile is prevented from leaking, and the head section of the device is fixed in the gallbladder.

The outer sleeve 6 is sleeved outside the inner core 1. The outer sleeve 6 is beneficial to fixing the puncture point and is convenient for puncture. The balloon 4 is exposed outside the outer sleeve 6.

The apparatus shown in fig. 1 further comprises: a first handle 7 and a second handle 8 connected with the tail end of the outer sleeve 6. The transfusion cavity 3 and the gas injection cavity 5 are respectively fixed on a first handle 7. The puncture needle 2 is an oblique cutting edge.

In some embodiments, the total device length is 2000 mm.

An example of the method of use of the invention is as follows:

as shown in fig. 2, the present invention employs an endoscope 9 for surgery. The front end of the endoscope 9 is provided with a transparent conical guide head 10. Before the gallbladder 11 is cut during the operation, the gallbladder 11 is punctured with the device of the present invention. As shown in fig. 3, after the puncture is successful, the balloon 4 at the head end is inflated so as to fully block the puncture hole, prevent bile 12 from leaking out during the operation, and firmly fix the head section of the device in the gallbladder 11 to prevent the device from slipping. Next, as shown in fig. 4, bile 12 in the gallbladder 11 is sufficiently aspirated through the puncture needle 2, the volume of the aspirated bile 12 is recorded as x ml, and then sterile physiological saline is injected. As shown in fig. 5, the bile is withdrawn again, and the sterile normal saline is injected again, and the process is repeated for a plurality of times until the withdrawn liquid is clear and transparent normal saline, and x ml of sterile normal saline is injected again, so that the exchange of bile 12 is completed. Then the air in the saccule 4 is discharged, the puncture needle 2 is pushed out, the gallbladder 11 is cut by the hook knife, at the moment, the sterile normal saline instead of the bile 12 is gushed from the gallbladder 11, and the pollution of the bile 12 to the abdominal cavity is effectively avoided. The transfusion cavity 3 can be used for sucking bile and injecting normal saline simultaneously, and after multiple times of suction, the normal saline can fully dilute the bile, thereby avoiding the pollution of the bile 12 to the abdominal cavity.

In conclusion, the sacculus is arranged behind the puncture needle of the gall bladder puncture-bile exchange device, the sacculus enters the gall bladder along with the puncture needle, the puncture opening can be blocked after the sacculus is expanded, bile is prevented from leaking, bile exchange is facilitated, and pollution of the bile to the abdominal cavity is effectively avoided after the bile exchange.
