Description

Technical Field

[0001] The utility model relates to the technical field of cyst puncture, in particular to a giant cyst puncture device. Background Art

[0002] Ovarian cysts are common ovarian lesions, ranging in size from a few centimeters to tens of centimeters. They may be benign, borderline, or malignant. Giant ovarian cysts may be borderline or malignant. To avoid the cyst fluid from overflowing into the abdominal cavity, it is best to remove it completely. However, sometimes, depending on the patient's condition, puncture and drainage of giant ovarian cysts are performed. The advantages are: 1. The abdominal wall incision is small, and recovery after surgery is fast; 2. After the cyst fluid is released, adhesions can be treated under direct vision; 3. Abdominal pressure gradually decreases to prevent heart failure.

[0003] At present, in order to avoid the overflow of cyst fluid, during the laparotomy puncture surgery for giant ovarian cysts, a small incision is first made in the abdomen, and then a gauze pad is used around the cyst to separate the tumor from the abdominal wall and abdominal cavity. Next, a purse-string suture is made at the intended puncture site. After that, a puncture instrument is used for puncture while tightening the purse-string suture. When the cyst shrinks to the point where it can be pulled out, the puncture instrument is removed, the purse-string suture is tightened, and a ligature is tied to prevent residual cystic fluid from overflowing, and finally the cyst is pulled out.

[0004] However, this existing laparotomy puncture technology for giant ovarian cysts has obvious disadvantages, including: 1. When performing purse-string suturing, if the cyst tension is high, inserting the needle too deep may cause the cyst to rupture, causing the cyst fluid to overflow and cause pollution; 2. It requires high cooperation between the puncturer and the person tightening the purse-string suture. The purse-string suture must be tightened twice during puncture and when the puncture needle is removed, otherwise it is easy to cause cyst fluid to overflow and cause pollution; 3. The puncturator used in the existing puncture technology is an ordinary puncturator. After puncture, the core tube is pulled out and then connected to the aspirator. There is also a risk of cystic fluid overflow during the process of pulling out the core tube. Utility Model Content

[0005] In view of the above situation, in order to make up for the deficiencies of the prior art, the purpose of the present utility model is to provide a giant cyst puncture device, which effectively solves the problems of easy overflow of cystic fluid and complicated operation during the existing giant cyst puncture.

[0006] The technical solution is as follows: the utility model comprises an upper and lower axial shielding tube, a puncture needle located in the shielding tube, a fixing disk is provided at the lower end of the shielding tube, a medical adhesive is provided at the lower end of the fixing disk, a receiving groove is coaxially provided at the lower end of the shielding tube, a ring-shaped sealing airbag is provided at the lower side of the receiving groove, the lower end of the sealing airbag can extend out of the receiving groove, an arc-shaped piston cylinder with an opening facing upward is provided at the upper side of the receiving groove, a piston plate which can move up and down is coaxially provided in the piston cylinder, an air intake pipe inserted into the sealing airbag is provided at the lower end of the piston cylinder, an air intake pipe located in front of the air intake pipe is provided at the lower end of the piston cylinder, and a connecting hose is provided at the upper end of the puncture needle.

[0019] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0020] Depend on Figures 1 to 7 The present invention comprises an upper and lower axial shielding tube 1, a puncture needle 2 located in the shielding tube 1, a fixing plate 3 is provided at the lower end of the shielding tube 1, a medical adhesive 4 is provided at the lower end of the fixing plate 3, a receiving groove is coaxially provided at the lower end of the shielding tube 1, a ring-shaped sealing airbag 5 is provided at the lower side of the receiving groove, the lower end of the sealing airbag 5 can extend out of the receiving groove, an arc-shaped piston cylinder 6 with an opening facing upward is provided at the upper side of the receiving groove, a piston plate 7 which can move up and down is coaxially provided in the piston cylinder 6, an air inlet pipe 8 inserted into the sealing airbag 5 is provided at the lower end of the piston cylinder 6, an air suction pipe 9 located in front of the air inlet pipe 8 is provided at the lower end of the piston cylinder 6, and a connecting hose 10 is provided at the upper end of the puncture needle 2.

[0021] In order to move the piston plate 7 up and down, the piston plate 7 is slidably connected to the piston cylinder 6. The upper end of the piston plate 7 is provided with an upper and lower axial pressure column 11. The upper end of the pressure column 11 penetrates the shielding tube 1 and is coaxially provided with a pressure plate 12.

[0022] In order to facilitate the resetting of the pressure plate 12 , a compression spring 13 is sleeved on the pressure column 11 and is located between the pressure plate 12 and the shielding tube 1 .

[0023] In order to facilitate the flow of gas, a first one-way valve 14 with an opening facing downward is provided in the air inlet pipe 8, and a second one-way valve 15 with an opening facing upward is provided in the air intake pipe 9.

[0024] In order to support the sealing airbag 5 , a fixing plate 16 fixed to the upper end of the sealing airbag 5 is provided in the accommodating groove.

[0025] In order to facilitate deflation, a deflation pipe 17 is provided on the right side of the sealing airbag 5 in an up-and-down axial direction. The upper end of the deflation pipe 17 passes through the shielding tube 1 and is detachably connected to a plug 18 .

[0026] In order to facilitate shielding, a baffle 19 is coaxially provided on the upper end of the shielding tube 1 , and an insertion slot 20 is provided on the baffle 19 , through which the puncture needle 2 can extend.

[0027] In order to facilitate air inhalation, an air inlet groove 21 communicating with the containing groove is provided at the upper end of the shielding tube 1 .

[0028] When the utility model is used, the protective film at the lower end of the medical adhesive 4 is first torn off and pasted on the surface of the huge cyst that needs to be punctured to achieve fixed limit of the shielding tube 1, and then the pressing plate 12 is pressed downward at this time, and the pressing plate 12 drives the pressure column 11 to move downward, and then drives the piston plate 7 to move downward in the piston cylinder 6, and squeezes the gas in the piston cylinder 6 into the sealing airbag 5 through the intake pipe 8. At this time, the second one-way valve 15 prevents the gas in the piston cylinder 6 from being squeezed out through the suction pipe 9, and then the pressing plate 12 is released. Due to the upward restoring force of the compression spring 13, the piston plate 7 is driven to move upward, and air is sucked into the piston cylinder 6 through the suction pipe 9. At this time, the first one-way valve 14 can prevent the gas in the sealing airbag 5 from being re-sucked into the piston cylinder 6;

[0029] The pressing plate 12 is repeatedly pressed downward and released, and the piston plate 7 continuously squeezes air into the sealing airbag 5 through the air inlet pipe 8, so that the sealing airbag 5 gradually expands, and the lower end of the sealing airbag 5 extends out of the receiving groove and contacts and compresses the surface of the patient's cyst to prevent the cystic fluid in the sealing tube from flowing out. At this time, the free end of the connecting hose 10 is connected to the negative pressure suction device, and then the puncture needle 2 is inserted into the patient's cyst to extract the fluid. The outflowing cystic fluid cannot flow out of the shielding tube 1 due to the obstruction of the sealing airbag 5;

[0030] After the extraction is completed, the leaked liquid in the shielding tube 1 is cleaned up, and then the shielding tube 1 is removed from the patient's cyst. At this time, the plug 18 is opened to shrink the sealing airbag 5 to its initial state, and then the shielding tube 1 is disinfected and the medical adhesive 4 is replaced.

[0031] Compared with the prior art, the utility model has the following beneficial effects: the shielding tube, sealing airbag, piston cylinder, etc. are provided, which can realize sealing of the operation area when aspirating cystic fluid from a giant cyst, preventing cystic fluid from overflowing and causing pollution and damage; at the same time, the negative pressure aspirator can be connected to continuously draw out the fluid, avoiding the damage caused by repeated withdrawal of the puncture needle by manual aspiration; the utility model has a simple structure, novel conception, is easy to use, and is highly practical.

[0032] It should be pointed out that, according to the needs of implementation, the various components described in the embodiments of the present utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of the present utility model.

[0033] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
