Abstract

The utility model relates to an arrangement device for prostate net-shaped brackets. The utility model comprises an outer tube, an inner tube and a core tube. The utility model is characterized in that the front part of the core tube is symmetrically provided with two shaft holes which are connected with two semicircular vanes by pin shafts. A conductor is composed of the two semicircular vanes. The middle part of the vane is movably connected with one transmission arm. The other end of each transmission arm is movably connected with the front end of a pull rod. The arrangement space for net-shaped brackets is arranged between the outer tube and the core tube. A locking mechanism of the outer tube is arranged between the outer tube and the inner tube. A locking mechanism of the inner tube is arranged between the core tube and the inner tube. The tail part of the core tube is provided with a washing joint which is communicated with the arrangement space for net-shaped brackets through the core tube. The utility model does not need a cystoscope, and the arrangement position is precise.

Description

Prostate network applier

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of prostate network applier that is applicable to the treatment male because of the caused urethral obstruction of prostatic hyperplasia.

At present, network must utilize the applier of being made up of inner and outer pipe to carry out under cystoscopic supervision when inserting prostate, need the limit to release network in the put procedure, applier is withdrawed from the limit, if mucous membrane of urethra is hemorrhage in the storing process, the visual field is unclear, can cause putting failure.

The purpose of this utility model provides a kind of without the cystoscope supervision, and the accurate positioning of storing network is simple to operate, the prostate network applier that is easy to promote.

Task of the present utility model is to realize like this, it comprises outer tube, interior pipe and core pipe, it is characterized in that: the anterior symmetry of core pipe has two axis holes, be connected with two semicircle blades forming guide by bearing pin in each axis hole, two semicircle blade middle parts are connected with a transmission arm by bearing pin respectively, two transmission arms are connected the front end of a pull bar by a bearing pin, the space that can place network around compression is arranged between outer tube and the core pipe front portion, outer tube retaining mechanism with interior pipe locking is arranged on the outer tube, the interior pipe retaining mechanism of locking with interior pipe is arranged on the core pipe, and the afterbody of core pipe has flush-through connection to communicate with placement network space by the core pipe.

This utility model needs only in use according to the prostatic urethra length of being inserted and the length of network, after the mensuration, with each retaining mechanism locking, can finish inserting of network blind looking down, do not need cystoscope, placement location is accurate, and is simple to operate, is easy to apply.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the structural representation of guide when open mode.

Drawing explanation: 1. manage retaining mechanism 10. flush-through connections 11. pull bar handles in the pipe 9. in the guide 2. transmission arms 3. outer tubes 4. networks 5. pull bars 6. core pipes 7. outer tube retaining mechanisms 8.

Further specify embodiment in conjunction with above accompanying drawing.This utility model is made up of outer tube 3, interior pipe 8 and core pipe 6 gap suit successively, is arranged with two axis holes at the front end of core pipe 6, is connected with the guide 1 that two semicircle blades are formed with bearing pin in each axis hole, external shape such as bullet-shaped when it is closed.The middle part of two semicircle blades of guide 1 is connected with a transmission arm 2 by bearing pin respectively, two transmission arms 2 are connected the front end of a pull bar 5 by a bearing pin, anterior between outer tube 3 and the core pipe 6 have one section can center on the space that network 4 is placed in compression, outer tube retaining mechanism 7 with interior pipe 8 lockings is arranged on the outer tube 3, interior pipe retaining mechanism 9 with interior pipe 8 lockings is arranged on the core pipe 6, the afterbody of core pipe 6 has flush-through connection 10 to communicate with placing the network space by the core pipe, can make things convenient for the water filling flushing.On the core pipe 6 length mark is arranged, afterbody has lockable pull bar handle 11.

When putting network 4, at first with network 4 compressions around being placed in core pipe 6 and the outer tube 3 forward spaces, cover by outer tube 3, after the combination as shown in Figure 1.Applier is inserted urethra, after guide 1 entered bladder, post-tensioning pull bar handle 11 was adjusted two blades fixedly making guide 1 and is opened that to be a horizontal line vertical with urethra, unclamp outer tube retaining mechanism 7 after being close to bladder neck, be pulled outwardly outer tube 3, by flush-through connection 10 perfusion hot salt brines, put network 4 in prostatic urethra simultaneously, the releasing lever handle 11 then, pushing drawing rod 5 closes up open two blades, extracts applier, finishes the storing task of network 4.
