Abstract
Description
Technical Field
[0001] The utility model belongs to the field of medical instruments, and in particular relates to a multi-chamber abscess cavity expander. Background Art
[0002] Multilocular abscesses are defined as multiple compartments of pus accumulation within an area of infection.
[0003] When treating multilocular abscesses, drainage is necessary to remove pus and promote healing.
[0004] Currently, puncture and drainage of pus from multi-chambered abscess cavities is particularly complicated, requiring multiple punctures of multiple pus accumulation areas, which not only increases the difficulty of the operation, but also increases the workload of medical staff.
[0005] Therefore, we proposed a multilocular abscess cavity expander to solve the above problems. Utility Model Content
[0006] In view of the problem that puncture and drainage of pus from multi-locular abscess cavities is particularly complicated and requires multiple punctures for multiple pus accumulations, which not only increases the difficulty of operation but also increases the workload of medical staff, the utility model provides a multi-locular abscess cavity expander.
[0007] The utility model solves the technical problem by adopting the following scheme: a multi-chamber abscess cavity expander, comprising a puncture catheter, a metal wire tube and a balloon, wherein a guide wire and a hose are arranged in the puncture catheter, and a groove is provided at the front end thereof;
[0008] The balloon is sheathed on the outside of the puncture catheter and is located behind the groove;
[0009] One end of the hose is connected to the balloon, and the other end is provided with a valve;
[0010] The metal wire tube is composed of a metal ring and N elastic wires, the N elastic wires are arranged around the outside of the balloon, one end of the elastic wire is fixedly connected to the metal ring, and the other end thereof is installed in the groove;
[0011] The metal ring is sleeved on the puncture catheter, and the metal ring can slide along the puncture catheter when the balloon expands or contracts.
[0012] Preferably, water or gas is stored in the balloon, and the valve body is a water injection valve or an air inflation valve.
[0013] Preferably, it also includes a traction wire, which is arranged on the outside of the puncture catheter, one end of which is connected to the metal ring, and the other end of the traction wire extends to the tail end of the puncture catheter.
[0014] Preferably, it also includes a spiral reinforcement wire, which is sleeved on the outside of the balloon and has two ends respectively connected to the inner wall of the metal wire tube.
[0015] Preferably, at least two drainage holes are provided at the front end of the puncture catheter.
[0016] Compared with the prior art, the beneficial effects of the utility model are:
[0017] 1. The utility model allows a puncture catheter to pass through the skin to allow a metal wire tube to enter a multilocular abscess cavity, and injects water or gas into the hose to expand a balloon. When the balloon expands, the metal wire tube is deformed. During the deformation of the metal wire tube, pressure is generated on the abscess cavity wall, and the intervals in the multilocular abscess cavity are broken to form a large pus accumulation area, so that the pus in the multilocular abscess cavity can be drained later, thereby reducing the difficulty of operation and improving the safety of the operation.
[0018] 2. The utility model sets a traction wire. When the gas or liquid in the balloon is discharged and the metal wire tube cannot shrink along with the balloon, the traction wire is pulled to move the metal ring along the puncture catheter, thereby stretching the metal wire tube and reducing the volume of the metal wire tube, so as to facilitate the removal of the metal wire tube from the multi-chamber abscess cavity.
[0019] 3. The utility model prevents the metal wire tube from being damaged due to pressure deformation during the balloon expansion process by arranging the spiral reinforcement wire. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0026] See also Figure 1-4 The utility model provides a technical solution of a multi-chamber abscess cavity expander:
[0027] Embodiment 1:
[0028] according to Figure 1-4 As shown, it comprises a puncture catheter 1, a metal wire tube 2 and a balloon 4. A guide wire 6 and a hose 5 are arranged inside the puncture catheter 1, and a groove is provided at the front end thereof. The guide wire 6 can guide the puncture catheter 1 to reach the multi-chamber abscess cavity.
[0029] The balloon 4 is sleeved on the outside of the puncture catheter 1 and is located behind the groove. Water or gas is stored in the balloon 4 .
[0030] One end of the hose 5 is connected to the balloon 4 , and the other end thereof is provided with a valve, wherein the valve body is a water injection valve or an air inflation valve, and the balloon 4 is expanded by injecting water or air into the hose 5 .
[0031] The metal wire tube 2 is composed of a metal ring and N elastic wires. The N elastic wires are arranged around the outside of the balloon 4. One end of the elastic wire is fixedly connected to the metal ring, and the other end thereof is installed in the groove.
[0032] The metal ring is sleeved on the puncture catheter 1 , and when the balloon 4 expands or contracts, the metal ring can slide along the puncture catheter 1 , thereby causing the metal wire tube 2 to deform.
[0033] When used specifically, the utility model is a multilocular abscess cavity expander. First, the guide wire 6 is passed through the skin to guide the puncture catheter 1, the balloon 4 and the wire tube 2 into the multilocular abscess cavity;
[0034] After the balloon 4 reaches the multilocular abscess cavity, water or gas is injected into the hose 5 to expand the balloon 4. When the balloon 4 expands, the metal wire tube 2 is deformed. During the deformation process, the metal wire tube 2 generates pressure on the abscess cavity wall, breaking the interval in the multilocular abscess cavity to form a large pus accumulation area, and then the pus in the multilocular abscess cavity is drained;
[0035] Finally, the gas or water in the balloon 4 is discharged to shrink the balloon 4 and the wire tube 2, and the catheter 1, the balloon 4 and the wire tube 2 are removed.
[0036] Embodiment 2:
[0037] On the basis of the first embodiment, Figure 1 and Figure 3 As shown, it also includes a traction wire 7, which is arranged on the outside of the puncture catheter 1, one end of which is connected to the metal ring, and the other end of the traction wire 7 extends to the tail end of the puncture catheter 1. By setting the traction wire 7, when the gas or liquid in the balloon 4 is discharged, the metal wire tube 2 cannot shrink as the balloon 4 shrinks, and by pulling the traction wire 7, the metal ring is moved along the puncture catheter 1, and then the metal wire tube 2 is stretched to reduce the volume of the metal wire tube 2, so as to facilitate the removal of the metal wire tube 2 from the multi-chamber abscess cavity.
[0038] Embodiment three:
[0039] On the basis of the first embodiment, Figure 3 and Figure 4 As shown, it also includes a spiral reinforcement wire 3, which is sleeved on the outside of the balloon 4, and its two ends are respectively connected to the inner wall of the metal wire tube 2. By arranging the spiral reinforcement wire 3, the metal wire tube 2 is prevented from being damaged due to pressure deformation during the expansion process of the balloon 4.
[0040] Embodiment 4:
[0041] On the basis of the first embodiment, Figure 1 and Figure 2 As shown, at least two drainage holes are provided at the front end of the puncture catheter.
