Abstract

The utility model relates to a smoke sucking, light controlling and light guiding tube for laser operations, which is a medical instrument for operations such as a laser surgical operation, etc. A smoke sucking tube, a conducting wire for transmitting and controlling photoelectric signals, and a fiber for transmitting laser are arranged in a soft metal sleeve whose diameter is less than 10mm. A pen-shaped metal suction head provided with a microswitch is arranged on the front end of the soft metal sleeve. The utility model has the three functions of sucking smoke, controlling light and guiding light when matched with a laser operation apparatus, an aspirator, etc. When an operator holds the suction head at different angles to gasify and cauterize diseased regions, particularly difficult operating regions such as oral cavities, nasal cavities, etc., the operator can control the output of laser at will and suck smoke in time.

Description

Smoke suction, light controlling and guiding tube for laser surgical operation

The medical apparatus and instruments that is used for operations such as laser surgery.

Using the laser fiber surgical device to carry out in section's laser surgerys such as surgery, skin and oral cavity, the laser irradiation diseased region of high-energy-density can produce smog, usually the operator hands the optical fiber of leaded light, be fixed on a certain position, step on the control photoswitch with single foot and control light output and undergo surgery, absorb smog and be placed on the edge, target area by the hand-held rubber suction pipe that is connected to suction pump of other special messenger.

According to the prior art data, laser fiber surgical device product all adopts simple optical fiber to conduct laser both at home and abroad, no smoking pipeline, adopt foot-operated switch and control light output, the laser operating apparatus product of being introduced in the YJ series laser fiber surgical device that these products such as Beijing Opto-electrical Technology Research Institute produce and Shanghai Institute of Laser Technology's volume " external laser product and manufacturer " book etc.Use the shortcoming of this series products to be: the operative site device disperses, and operator's range of activity is little, and movement response is slow, and particularly when boil on the nape opposite the mouth nasal cavity etc. was difficult for the operating position operation, the smoking effect was bad.

The purpose of this utility model provides the smoking control photoconduction electro-optical device of a kind of compact conformation, soft pliable, to overcome the deficiency of the said goods.

Structure of the present utility model sees accompanying drawing for details.

Fig. 1 is the outline drawing of whole device, and ratio is 1:1.

Fig. 2 is the cutaway view of suction nozzle part, and ratio is 2:1.

Fig. 3 is the outline drawing of middle body (2), and ratio is 2:1.

Fig. 4 is the cutaway view of soft tube (8) part, and ratio is 2:1.

This utility model is by anterior cannula (1), middle body (2), handle pipe (3), microswitch (4), long screw (5), short screw (6), insulated sleeve (7), soft tube (8), optical fiber (9), suction pipe (10), duplex wire (11), base (12) is formed.

Its total is: anterior cannula (1) and middle body (2) front threads socket, anterior and middle body (2) the rear threads socket of handle pipe (3), anterior and the level and smooth socket in handle pipe (3) rear portion of soft tube (8), fixing by two short screws (6), the level and smooth socket of its afterbody and base (12), fixing by two short screws (6), optical fiber (9), suction pipe (10), duplex wire (11) passes soft tube (8) and enters in the handle pipe (3), it is little lateral opening that optical fiber (9) passes middle body (2) top one again, little bending enters anterior tubule endoporus along a skewed slot, until exposing naked fibre, body (2) rear portion extra heavy pipe in suction pipe (10) socket, microswitch (4) is installed in one square groove of middle body (2) middle part, fixing by long screw (5), its payment to a porter is from two little lateral opening passing, weld with duplex wire (11), entangle by insulated sleeve (7), the middle anterior tubule external rear wall of body (2) is with a upper of a shoe shape structure, be connected with a part of truncated cone, its outer wall and anterior cannula (1) inwall connects airtight and touches, make between tubule outer wall and anterior cannula (1) inwall gap form the smoking passage, this passage and miscellaneous part isolation with middle body (2) rear portion extra heavy pipe endoporus and suction pipe (10) endoporus.

During arrangement works described in the utility model, base (12) is fixed on the laser operating apparatus casing, optical fiber (9) and laser instrument coupling, suction pipe (10) is connected with suction pump, and duplex wire (11) connects the low-voltage relay switch of a control light output, behind the unlatching suction pump, can produce a conical negative pressuren zone in the suction nozzle front portion, the output of microswitch (4) may command light, the smog that is produced during operation can in time be inhaled into suction nozzle, in the smoking passage enters the suction pump filtering flask.

This utility model organically combines smoking, control light and three kinds of functions of leaded light, makes the performance of existing procucts improve a step.

Implement used parts such as the microswitch (4) of this utility model, long screw (5), short screw (6), insulated sleeve (7), soft tube (8), optical fiber (9), suction pipe (10), duplex wire (11) all can adopt existing product, and anterior cannula (1), middle body (2), handle pipe (3), base (12) adopt copper metal or stainless steel material to be processed into.
