Description
Technical Field
The application relates to a laparoscope ultrasonic probe sleeve with an adjustable water sac, which is particularly suitable for improving the bonding of a laparoscope ultrasonic probe and the surface of a liver with cirrhosis and belongs to the technical field of medical instruments.
Background
Cirrhosis is a clinically common chronic progressive liver disease, diffuse liver damage is formed by long-term or repeated action of one or more causes, and patients with cirrhosis have hard liver texture and uneven surface due to hardened nodules. When a laparoscopic liver surgery is performed, a laparoscopic ultrasonic probe is often required to probe the liver so as to determine the position of a tumor and the relationship between the tumor and an important pipeline to guide a surgery path and prevent small tumors from being missed. According to the ultrasonic imaging principle, the ultrasonic probe needs to be tightly attached to the surface to be checked, so that the existence of air between contact surfaces is avoided, and the influence of sound wave reflection and scattering caused by gas on imaging of rear tissues is prevented. Due to the existence of cirrhosis, the endoscopic probe cannot be well attached to the uneven and hard liver surface, and the interference of air in the formed cavity will seriously affect the accurate positioning of the endoscopic probe on the liver tumor. In the case of performing ultrasonic examination in an open liver surgery, the related art often uses flowing water to avoid poor adhesion between the probe and the hardened liver surface, however, in a laparoscopic liver surgery, the method of increasing adhesion using flowing water is difficult and unstable. For ultrasonic exploration of uneven surfaces, the irregular gap between a hard ultrasonic probe and a detected surface is filled up by increasing the dosage of a coupling agent or an acoustic pad clinically, but the two methods are not suitable for laparoscopic surgery. There is therefore a need for a sound guide probe cover that improves the fit of an ultrasound probe to the surface of the liver so that hardened liver can be easily ultrasonically examined in laparoscopic surgery.
SUMMERY OF THE UTILITY MODEL
The technical problem that this application will be solved leads to ultrasonic probe and the not good problem of liver surface laminating because of liver sclerosis surperficial unevenness.
In order to solve the technical problem, the technical scheme of the application is to provide a laparoscope ultrasonic probe sleeve with an adjustable water sac, which is used for being attached to the surface of a probe and is characterized by comprising a rubber sleeve sleeved on the probe, wherein the water sac is arranged outside the rubber sleeve and faces the probe, and is communicated to an external liquid injector through a water injection pipe; the water sac completely covers the probe.
Preferably, the size of the rubber sleeve is smaller than that of the probe, and the rubber sleeve is tightly attached to the probe due to the tensile elasticity.
Preferably, the water injection pipe is a plastic transparent pipe and is in seamless connection with the water bag.
The water bag has the advantages that the equipment is simple and small, the manufacturing cost is low, and the water bag is adjustable; the problem of poor liver cirrhosis ultrasonic imaging is solved by adopting the simplest structure.

Detailed Description
In order to make the present application more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
Examples
According to the ultrasonic imaging principle, the ultrasonic probe needs to be tightly attached to the surface to be checked, so that the existence of air between contact surfaces is avoided, and the influence of sound wave reflection and scattering caused by gas on imaging of rear tissues is prevented. Due to the existence of cirrhosis, the endoscopic probe cannot be well attached to the uneven and hard liver surface, and the interference of air in the formed cavity will seriously affect the accurate positioning of the endoscopic probe on the liver tumor. The soft deformable water sac is additionally arranged on the hard ultrasonic probe, so that the probe can be well mediated to be attached to the surface of the liver, the formation of air cavities is avoided, and the best ultrasonic imaging effect is achieved.
FIG. 1 is a schematic view of a laparoscopic ultrasound joystick 1 having a diameter of about 8mm and a probe 11 portion having a length and width of about 2cm by 0.5 cm;
fig. 2 and 3 show the laparoscopic ultrasound probe cover with an adjustable water sac according to the present embodiment, the rubber sleeve 2 is used to cover the position of the probe 11 at the front end of the operating rod 1, and has a diameter of 4mm and a length of 5cm, so that the probe 11 (with a diameter of 8mm) can be tightly covered, and cannot be displaced or slip due to the movement of the probe 11, and a proper amount of liquid can be added between the rubber sleeve 2 and the probe 11 to discharge air bubbles;
a water bag 3 is arranged outside the rubber sleeve 2 and the probe 11 faces the position, and the water bag 3 is communicated to an external liquid injector 5 through a water injection pipe 4; the water injection pipe 4 is a plastic transparent pipe, has the pipe diameter of 2mm and the length of 50cm, and is in seamless connection with the water bag 3; the injector 5 can adopt a needle cylinder, which is shown as a 5mm needle cylinder; the water sac 3 is attached to the rubber sleeve 2, the position of the water sac 3 is equivalent to the position of the probe 11 on the operating rod 1, the water sac is about 2cm multiplied by 0.5cm, the water sac is attached to the rubber sleeve 2 when no water exists, the water sac can conveniently enter and exit a 1.2cm puncture sleeve hole, the probe 11 can be completely covered after water injection expansion, the water sac 3 is guaranteed to be completely bulged by adjusting the amount of injected water, and the water sac is soft enough to be completely attached to the surface of a hardened liver.
The key point of the structure of the embodiment is to eliminate air in each part so as to avoid the influence of bubbles on the ultrasonic image; the use process is as shown in fig. 4 and 5, the water sac 3 completely covers the probe 11, fully swells after water injection expansion, is soft enough to be completely attached to the hardened liver surface, and greatly improves the liver exploration effect of the ultrasonic probe.
The application has the advantages; the equipment is simple and small, the manufacturing cost is low, and the water bag is adjustable; the problem of poor liver cirrhosis ultrasonic imaging is solved by adopting the simplest structure.
