Abstract
The utility model relates to an auxiliary instrument combined with an endoscope disposal instrument, in particular to a screw rod type handle for the endoscope disposal instrument. a sliding clamp ring is sleeved on a spiral receding side of a screw tube, a nut is connected with a precession side of the screw tube through threads, sliding grooves are formed in the spiral receding direction and in the precession direction of the screw tube, a locking clamping head is arranged at an end of the precession side of the screw tube, and a clamp handle ring is fixedly connected with an end of the spiral receding side of the screw tube. The nut is spirally backed and drives the sliding clamp ring to slide, so an operating line is downwards moved and tightened, and extracting force and trituration force of an operating end are strengthened.
Description
[technical field]
This utility model relates to the assistive device of being combined with the endoscopic surgical apparatus, is specifically related to a kind of endoscopic surgical apparatus spiral rod type handle.
[background technology]
Known, usually need scope treatment apparatus (foreign body forceps) that calculus in the digestive tract or foreign body are extracted, but part gastric calculus or foreign body volume are bigger, are difficult to directly take out from patient's tract, therefore after needing earlier bulky gastric calculus or foreign body cut rubbing, progressively take out.The handle of existing common scope treatment apparatus postpones the open and close of drawing the control device working end before relying on operator to the sliding clamp ring, pull strength to operating line is limited, can't bigger to volume, scleroid gastric calculus or foreign body extract operations such as rubbing.The capstan winch formula handle that the special-purpose gastrolith sickle of import brand adopts has volume big, the difficult shortcoming of controlling.Therefore, provide a kind of scope special-purpose spiral handle, the gear ratio that it utilizes screwed pipe, nut structure has improved the operating physical force of scope treatment apparatus, thereby realizes large volume gastric calculus or foreign body are cut the process that rubbing is extracted again
[summary of the invention]
In order to solve above-mentioned deficiency of the prior art and defective, this utility model provide a kind of be convenient to scope treatment apparatus working end to the gastrolith in the digestive tract or foreign body extract, the spiral rod type handle of operation such as rubbing.
For achieving the above object, design a kind of endoscopic surgical apparatus spiral rod type handle, revolve at screwed pipe and to move back the side sheathed sliding clamp ring that slides, at the screwed pipe precession side nut that is threaded, screwed pipe moves back direction and has sliding tray revolving along precession, screwed pipe is provided with the locking dop in the termination of precession side, and described screwed pipe moves back fixedly connected pincers handle ring on the side head revolving.
Said structure has following prioritization scheme:
Described sliding clamp ring is provided with lock screw.
Described pincers handle ring is fixed on the screwed pipe by first connection tube.
Described locking dop is fixed on the screwed pipe by second connection tube.
Described screwed pipe surface is provided with annular knurl.
This utility model has the following advantages compared to existing technology:
1. the helix tube type of helix tube type handle pincers handle has sliding tray, is furnished with nut, and surface knurling is handled, and is convenient to precession.Screwed pipe, nut preferentially adopt metal material, improve intensity.
2. the sliding clamp ring places the nut rear side, can be connected with active line and the flexible metal hose sheath of apparatus, can before and after the sliding tray of screwed pipe, easily move, after stressed, revolve withdrawing nut, nut drives the sliding clamp ring, move, tighten up after making operating line, make scope treatment apparatus working end steel wire to the gastrolith in the digestive tract or foreign body extract, operation such as rubbing.
3. the spiral handle front end adopts the standard lock dop, can connect the metal tube sheath of scope treatment apparatus, and the suitability is good.
[description of drawings]
Fig. 1 is the structural representation of embodiment 1;
1. pincers handle rings, 2. first connection tubes, 3. screwed pipes, 4. sliding clamp rings, 5. nuts, 6. active line pull bars, 7. second connection tubes, 8. lock screws, 9. locking dops, 10. sliding trays, 11. precession sides 12. are revolved and are moved back side among the figure.
[specific embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearer, by reference to the accompanying drawings this utility model is further elaborated.Production equipment among the application all is the common equipment of this area, should be appreciated that specific embodiment described herein only in order to explaining this utility model, and is not used in restriction this utility model.
Embodiment 1
When being used on the active line pull bar of endoscopic surgical apparatus:
As shown in Figure 1, revolve at screwed pipe 3 and to move back the side sheathed sliding clamp ring 4 that slides, at the screwed pipe 3 precession sides nut 5 that is threaded, screwed pipe 3 has sliding tray 10 revolving the direction of moving back along precession, screwed pipe 3 surfaces are provided with annular knurl, screwed pipe 3 is provided with locking dop 9 in the termination of precession side, described screwed pipe 3 moves back fixedly connected pincers handle ring 1 on the side head revolving.Described sliding clamp ring 4 is provided with lock screw 8.Described pincers handle ring 1 is fixed on the screwed pipe 3 by first connection tube 2.Described locking dop 9 is fixed on the screwed pipe 3 by second connection tube 7, and locking dop 9 can use with the assembling of correlation type scope treatment apparatus.
Active line pull bar 6 passes from screwed pipe 3 and is fixing with sliding clamp ring 4.
In the operating process, control helix tube type taper knob is got gastric calculus or foreign body etc. in the digestive tract, and operator pulling sliding clamp ring is to tightening up, and it is mobile backward thereupon to revolve withdrawing nut 5 drive sliding clamp rings 4, draw by 6 pairs of operating lines of pull bar, thereby strengthen cover power taking and the rubbing power of working end.
Claims (5)
1. endoscopic surgical apparatus spiral rod type handle, it is characterized in that revolving at screwed pipe and move back the side sheathed sliding clamp ring that slides, at the screwed pipe precession side nut that is threaded, screwed pipe moves back direction and has sliding tray revolving along precession, screwed pipe is provided with the locking dop in the termination of precession side, and described screwed pipe moves back fixedly connected pincers handle ring on the side head revolving.
2. endoscopic surgical apparatus spiral rod type handle as claimed in claim 1 is characterized in that described sliding clamp ring is provided with lock screw.
