Description

Device for treating ganglion

Technical Field

The invention relates to the technical field of medical appliances, in particular to an appliance for treating ganglion cyst.

Background

Ganglion cysts are cystic tumors that occur within the ganglion of the joints, a condition that results from degeneration of the connective tissue surrounding the joint capsule. The cyst contains colorless, transparent, orange and yellowish thick mucus, which is frequently found on the dorsum of the wrist and the dorsum of the foot. The cyst fluid is extracted by puncture, and then the adjuvant therapy medicine, such as adrenocortical hormone or hyaluronidase, is injected, which has certain curative effect on treating ganglion cyst and has small wound. However, the existing devices generally adopt the method of firstly extracting the sac liquid and then injecting the medicine for auxiliary treatment, so that the medicine for auxiliary treatment or the soluble liquid medicine for melting the sac liquid can not be injected while extracting the liquid, thereby causing the need of multi-step operation and low treatment efficiency.

The clinical operation steps of the invention are as follows:

1. when the accumulated liquid is extracted from the ganglion of a patient, the synchronous positions of the first rubber plug 10 and the second rubber plug 13 are close to the suction pipe 1 and the head end (the left end in the figure 1) or the middle part in the medicine adding pipe 6, the double-channel puncture needle 5 is firstly inserted into the accumulated liquid part of the cyst, and then the double-channel puncture needle 5 is fixed through a fixing bandage, so that the operation of medical personnel is facilitated, at the moment, the medical personnel pulls the handle 11 to move towards the tail end, and the handle 11 can drive the first rubber plug 10 and the second piston rod 19 to drive the second rubber plug 13 to synchronously move through the first piston rod 9 in the moving process, so that the left side of the first rubber plug 10 forms a negative pressure shape, and under the action of the pressure, the blocking block 16 in the sleeve 2 leaves from the sleeve 2 until the blocking block is positioned outside;

2. meanwhile, the accumulated liquid flows through the other channel of the two-channel puncture needle 5, the pipette 4 and the sleeve 2 in sequence and then is drained into the suction tube 1 (the accumulated liquid enters the suction tube 1 from the sleeve 2 as shown by the arrow direction in fig. 3), when the medical staff stops pulling the handle 11, the pressure on the blocking block 16 is gradually weakened, when the pressure is smaller than the elastic force generated by the reset motion of the reset spring 18, the blocking block 16 can move into the sleeve 2 under the elastic force of the reset spring 18, and the blocking block 16 in the liquid discharge tube 3 is always in the liquid discharge tube 3 in the process;

3. in the process of pulling the handle 11 to move towards the tail end in the step 2, the accumulated liquid of the ganglion is prevented from entering the medicine adding pipe 6 due to the second rubber plug 13 or the one-way valve 20 with another structure;

4. promote first piston rod 9 through handle 11 again, second piston rod 19 moves to the head end, the shutoff piece 16 that is in fluid-discharge tube 3 this moment is pushed outwards, until leaving in fluid-discharge tube 3, and then can pass through fluid-discharge tube 3 with the hydrops in the suction tube 1 and discharge, the medicine that the second plug 13 will be in the adjunctie therapy in the left side dosing tube 6 simultaneously, like adrenal cortex hormone or hyaluronidase or get up the soluble liquid medicine that melts to the cyst fluid through connecting pipe 7, another passageway of two-channel pjncture needle 5 is crowded in patient's wrist ganglion, be used for adjunctie therapy, when needing to take out the fluid once more, it can to repeat above operation.

According to the invention, through arranging two independent opening and closing structures, the blocking block 16 is in sealing fit with the limiting ring 15, the sleeve 2 and the liquid discharge pipe 3, the handle 11 is pulled to enable the left side of the first rubber plug 10 to form a negative pressure state, accumulated liquid can be drained into the suction pipe 1 under the action of the negative pressure, the pulling force acting on the handle 11 is removed, the blocking block 16 is moved into the sleeve 2 under the action of the elastic force of the return spring 18, and the blocking block 16 positioned in the liquid discharge pipe 3 is always positioned in the liquid discharge pipe 3 in the process; the first piston rod 9 and the second piston rod 19 are pushed by the handle 11 to move leftwards, accumulated liquid in the suction tube 1 can be discharged through the liquid outlet pipe, and medicines for auxiliary treatment in the medicine feeding pipe 6, such as adrenocortical hormone or hyaluronidase or soluble liquid medicine for melting cyst liquid, can be extruded into the connecting pipe 7 by the second rubber plug 13 and then is sent into a ganglion of the wrist of a patient; when needing to take out liquid again, repeat above operation, consequently medical personnel only need insert binary channels pjncture needle 5 when taking out liquid many times, not only can reduce patient's misery, can also alleviate the secondary injury of puncture to the patient.

According to the invention, the two-channel puncture needle 5 is fixed through the fixing band, so that the operation of medical staff is convenient, the two-channel puncture needle 5 can inject the medicine in the medicine adding pipe 6 into the ganglion for (auxiliary) treatment in the process of extracting the accumulated liquid of the ganglion, the connection or the disconnection of the sleeve pipe 2 and the liquid discharge pipe 3 can be well realized through the sealing and matching of the blocking block 16, the limiting ring 15, the sleeve pipe 2 and the liquid discharge pipe 3, the sealing effect is good, so that the suction treatment of the cyst liquid of the ganglion is convenient, the negative pressure liquid suction effect can be improved, the medicine in the medicine adding pipe 6 is injected into the ganglion for treatment by adopting the sealing cover 8 and the sealing ring 12, and the push-pull movement of the second piston rod 19 can be more stable.

The invention can also be applied to effusion of tissues at other parts, such as effusion for treating popliteal cyst and the like.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
