Abstract

The invention discloses an abdominal cavity operation speculum which comprises a supporting bracket connected to a bed body, a sleeve is arranged on the supporting bracket, two abdomen opening arms which move relatively driven by a drive mechanism are connected in the sleeve in a sliding mode, the outwards-expansion ends of the two abdomen opening arms are provided with abdomen opening plates respectively, the two abdomen opening arms are provided with plug-in long grooves respectively, pulling rods with the widths being smaller than the widths of the plug-in long grooves are inserted in the plug-in long grooves, a visceral organ traction plate is arranged on the end portion, stretching into the space between the two abdomen opening arms, of each pulling rod, and locking bolts extending into the plug-in long grooves are connected to the abdomen opening arms in a threaded mode. The abdominal cavity operation speculum has the advantages of guaranteeing the angle and force for stretching a visceral organ and guaranteeing operation vision exposure.

Description

A kind of abdominal operation speculum

Technical field

The invention belongs to the abdominal operation instrument field, specifically a kind of for strutting the abdominal operation speculum in abdominal cavity.

Background technology

When doing abdominal operation, need to do otch from stomach wall, abdominal operation speculum is stretched into and strutted stomach wall from incision, visual area is exposed.Existing abdominal operation speculum comprises two abdomen arms that an end is hinged, and a web respectively is equipped with in the bottom of two abdomen arms, opens an abdomen arm during use and makes two abdomen arms form certain angle, and a web props up stomach wall, thereby visual area is exposed.The shortcoming that this abdominal operation speculum exists is: abdominal visceral browser is many, while being performed the operation for a certain internal organs, need the multidigit medical personnel to use medical appliance from all directions tractive other organs, while being performed the operation, medical personnel are difficult to guarantee angle and the dynamics of tractive internal organs, thereby it is unstable easily to cause visual area to expose, strengthen medical personnel's labor intensity, also easily extended operating time, be unfavorable for patient's rehabilitation.

Summary of the invention

The technical problem to be solved in the present invention is to provide angle and the dynamics that can guarantee the tractive internal organs and can guarantees a kind of abdominal operation speculum that visual area exposes.

For solving the problems of the technologies described above, the speculum of abdominal operation with following construction features is provided: this abdominal operation speculum comprises the bracing frame be connected on a body, sleeve is housed on bracing frame, slidably connect two abdomen arms that driven relative motion by driving mechanism in sleeve, overhanging end on two abdomen arms is equipped with respectively a web, its construction features is: the cross section of two abdomen arms is rounded and be set with cylindrical sleeve outward, be bolted with on cylindrical sleeve it is fastened on to the bolt on an abdomen arm, also be connected with and install cover on cylindrical sleeve, install and put the clamping screw that is fitted with pull bar and is bolted with locking pull bar extension elongation, pull bar stretches into two ends between the abdomen arm visceral pulling plate is housed.

Described driving mechanism comprises the gear shaft be rotatably connected on sleeve, on two abdomen arms, the tooth bar be slidably connected in sleeve is housed respectively, and while and two tooth bar meshed gears are housed on gear shaft, and the overhanging end of gear shaft also is equipped with and screws handgrip.

The top pinch roller be pressed against on tooth bar also is housed in sleeve.

After adopting said structure, when doing abdominal operation, an abdomen arm of this abdominal operation speculum is stretched into from incision, drive two abdomen arm relative motioies by driving mechanism, a web that is arranged on an abdomen arm end props up stomach wall and struts stomach wall, the inner extending end of pull bar is stretched into to intraperitoneal, catch on internal organs by the visceral pulling plate after arriving assigned address, and by clamping screw, pull bar is locked, thereby pushing other organs aside exposes the internal organs that need to be performed the operation, use this abdominal operation speculum can make visual area expose fully, stir other organs with the visceral pulling plate of pull bar inserting end and replace medical personnel's manual operations, and can be by sleeve and abdomen arm coordinate to adjust the tractive angle, dynamics while being conducive to control the tractive internal organs and angle, and greatly reduce medical personnel's working strength.Therefore the present invention has advantages of angle and the dynamics that can guarantee the tractive internal organs and can guarantee that visual area exposes.

The accompanying drawing explanation

Below in conjunction with accompanying drawing, the present invention is further illustrated:

Fig. 1 is structural representation of the present invention;

Fig. 2 be in Fig. 1 A to schematic diagram;

Fig. 3 is the schematic diagram along in Fig. 1, the B-B line is analysed and observe;

Fig. 4 is the schematic diagram along in Fig. 1, the C-C line is analysed and observe.

The specific embodiment

Abdominal operation speculum as shown in drawings, it comprises the bracing frame 1 be connected on a body, the lower end of bracing frame 1 can be provided with elastic clip for the bedstead being held in a body, also sleeve can be set, the mode be bolted is connected on bedstead, the concrete structure of this bracing frame 1 is prior art, do not repeat them here, sleeve 2 is housed on bracing frame 1, slidably connect two abdomen arms 3 that driven relative motion by driving mechanism in sleeve 2, overhanging end on two abdomen arms 3 is equipped with respectively a web 4, as shown in fig. 1, the flat segments of opening web 4 is hinged on an end of abdomen arm 3, under web 4, the section of stretching is curved, be convenient to prop up stomach wall, the cross section of two abdomen arms 3 is rounded and be set with cylindrical sleeve 5 outward, be bolted with on cylindrical sleeve 5 it is fastened on to the bolt 14 on an abdomen arm 3, also be connected with on cylindrical sleeve 5 and install cover 8, install on cover 8 clamping screw 15 that is fitted with pull bar 7 and is bolted with locking pull bar 7 extension elongations, pull bar 7 stretches into two ends between abdomen arm 3 visceral pulling plate 6 is housed, can adjust the traction angle of internal organs towing plate by the cooperation of cylindrical sleeve and an abdomen arm, the pull bar of plug-in mounting can be adjusted and pull out distance, after the internal organs towing plate 6 of pull bar front end pulls internal organs and stretch out after angle and length determines, can be by clamping screw 15 locking pull bars 7, thereby tractive angle and the tractive dynamics of internal organs have been guaranteed.

As shown in Figure 1 and Figure 4, driving mechanism comprises the gear shaft be rotatably connected on sleeve 2, on two abdomen arms 3, the tooth bar 9 be slidably connected in sleeve 2 is housed respectively, while and two tooth bar 9 meshed gears 11 are housed on gear shaft 10, the overhanging end of gear shaft 10 also is equipped with and screws handgrip 12.For guaranteeing the slip stationarity of tooth bar 9, the top pinch roller 13 be pressed against on tooth bar 9 also is housed in sleeve 2.

Be only for example more than to best mode for carrying out the invention for example, do not form restriction of the present invention.As the engineers and technicians of the art, any all should be within protection scope of the present invention based on the present invention the equivalents done in conjunction with prior art.
