Abstract

The utility model relates to a vertebral expansion balloon catheter which consists of a balloon (1), a core tube (3), an outer tube (4), developing rings (2) and a handle (5), wherein the handle (5) is provided with an injection port (7) and a supporting screw port (6). One end of balloon (1) is fixedly connected with the core tube (3); the other end of the balloon (1) is fixedly connected with the outer tube (4); the number of the developing rings (2) is two, and the two developing rings (2) are fixed on the core tube (3) and are positioned at the two ends of the balloon (1); the core tube (3) penetrates into the outer tube (4) and is fixedly connected with the outer tube (4); the outer tube (4) is fixedly connected with the handle (5); and the connection between the head of the balloon (1) and the core tube (3) is in an inwardly-concave structure (1-1). The vertebral expansion balloon catheter can effectively increase the balloon expansion volume and results in more sufficient expansion, thereby further improving the quality of an operation.

Description

The vertebral body expansion of balloon catheter

Technical field

This utility model relates to a kind of vertebral body expansion of balloon catheter, belongs to medical instruments field, when being used to carry out the kyphoplasty art, uses, and is one of apparatus commonly used when carrying out the vertebral body expansion.

Background technology

In recent years, in the clinical medicine treatment, the kyphoplasty art has obtained extensive use as the osteoporotic method of a kind of main treatment.When the collapse of vertebra diseased region carried out dilation therapy in to the patient body, the vertebral body expansion of balloon catheter can stretch in the body through the puncture epitheca, expands the vertebral body of subsiding, and fixedly hinders vertebra so that inject bone cement.Through puncture epitheca expansion vertebral body, Wicresoft hinders, misery is little, so the kyphoplasty art is a kind of well received Therapeutic Method.

In the vertebral body expansion of balloon catheter of prior art; Sacculus body head end and core pipe jointing part position protrusion are outside at sacculus, in the balloon expandable process, have reduced the dischargeable capacity of balloon expandable, have reduced expansion effect; Increased operating difficulty, thereby made the operation downgrade.

Summary of the invention

The purpose of this utility model provides a kind of vertebral body expansion of balloon catheter that can increase the balloon expandable volume effectively, improve the operation quality.

The technical scheme that realizes above-mentioned purpose is: a kind of vertebral body expansion of balloon catheter, to form by the handle of sacculus, core pipe, outer tube, development ring and band liquid injection port and supporting wire mouth, and an end of sacculus is fixedly connected with the core pipe; The other end is fixedly connected with outer tube, and the ring that develops has two, all is fixed on the core pipe; And be positioned at the two ends of sacculus; The core pipe is through in the outer tube and with outer tube and is fixedly connected, and outer tube is fixedly connected with handle, and the position that the sacculus head is connected with the core pipe is a concave inward structure.

After adopting technique scheme, concave inward structure is adopted in sacculus head of this utility model and core pipe junction, makes sacculus can arrive more depths of vertebral body, has increased the expansion volume effectively, makes expansion more abundant, thereby has improved the operation quality effectively.

Description of drawings

Fig. 1 is the structural representation of this utility model.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment this utility model is done further detailed explanation.

As shown in Figure 1, a kind of vertebral body expansion of balloon catheter is made up of the handle 5 of sacculus 1, core pipe 3, outer tube 4, develop ring 2 and band liquid injection port 7 and supporting wire mouth 6; One end of sacculus 1 is fixedly connected with core pipe 3, and the other end is fixedly connected with outer tube 4, and the ring 2 that develops has two; All be fixed on the core pipe 3, and be positioned at the two ends of sacculus 1, core pipe 3 is through in the outer tube 4 and with outer tube 4 and is fixedly connected; Outer tube 4 is fixedly connected with handle 5, and the position that sacculus 1 head is connected with core pipe 3 is concave inward structure 1-1.

The method for using of this utility model is following:

Insert in the vertebra service aisle of getting through in advance taking out flat sacculus 1, under the monitoring of X line fluoroscopic machine, observe foley's tube development ring 2 positions; After guaranteeing to arrive correct position, foley's tube liquid injection port 7 is injected an amount of contrast agent, and keep watch on the injection rate and the expansion situation of injecting back sacculus body of contrast agent constantly; Vertebral body to originally subsiding restores, be expanded to perfect condition after, take out flat foley's tube; Withdraw from foley's tube; Utilize the bone cement tucker to fill bone cement then, fill with the spinal column cavity, reach and recover to stablize the purpose of vertebral body.

Claims

1. vertebral body expansion of balloon catheter; Handle (5) by sacculus (1), core pipe (3), outer tube (4), develop ring (2) and band liquid injection port (7) and supporting wire mouth (6) is formed, and an end of sacculus (1) is fixedly connected with core pipe (3), and the other end is fixedly connected with outer tube (4); The ring (2) that develops has two; All be fixed on the core pipe (3), and be positioned at the two ends of sacculus (1), core pipe (3) is through in the outer tube (4) and with outer tube (4) and is fixedly connected; Outer tube (4) is fixedly connected with handle (5), it is characterized in that: the position that sacculus (1) head is connected with core pipe (3) is concave inward structure (1-1).
