Abstract

The utility model discloses a kind of biliary tract bougies, including popping one's head in, connecting the feeler lever of the probe and the tail portion of the connection feeler lever；Described to pop one's head in as diameter from intermediate respectively to the diminishing cylinder in both ends, the maximum value of probe diameter is greater than 4mm, and the diameter of probe is greater than the diameter of feeler lever and tail portion, and the lengthwise dimension length of probe is greater than the diameter popped one's head in；The probe diameter of increasing and the size for increasing probe length direction make probe and the contact area of biliary tract inner wall become larger, reach the better expansion effect of biliary tract.

Description

A kind of biliary tract bougie

Technical field

The utility model relates to the field of medical instrument technology, specially a kind of biliary tract bougie.

Background technique

Biliary tract bougie is a kind of common medical operating auxiliary tool in medical operating, and gallbladder is first used in operation on biliary tract Road bougie is completed to place drainage tube supporting drainage to after bile duct exploration expansion.

The probe diameter and length dimension of biliary tract bougie used in usual medical operating are shorter, so that the entirety of probe Size is smaller, and when causing probe movable in biliary tract, probe can not touch biliary tract inner wall, or pop one's head in and the contact of biliary tract inner wall Area is smaller, is unable to complete to biliary tract expansion.

Utility model content

The purpose of this utility model is to provide for a kind of biliary tract bougie, the probe diameter of increasing and increases probe length The size for spending direction makes probe and the contact area of biliary tract inner wall become larger, reaches the better expansion effect of biliary tract.

In order to achieve the above-mentioned object of the invention, the utility model uses a kind of following technical scheme: biliary tract bougie, including visits The tail portion of head, the feeler lever of the connection probe and the connection feeler lever；The probe be diameter from it is intermediate respectively to both ends by Tapered small cylinder, the maximum value of probe diameter are greater than 4mm, and the diameter of probe is greater than the diameter of feeler lever and tail portion, the length of probe Spend the diameter that direction dimensions length is greater than probe.

Compared with prior art, it using a kind of biliary tract bougie of above-mentioned technical proposal, has the following beneficial effects:

It pops one's head in as diameter from intermediate respectively to the diminishing cylinder in both ends, and pops one's head in and be located at biliary tract interior diameter greater than gallbladder The contact area of the radius in road, detecting head surface and biliary tract inner wall increases, and expansion effect is more preferable；And increase the length ruler of probe It is very little, further increase the contact area of detecting head surface Yu biliary tract inner wall.

Preferably, the probe protrudes into the head that one end in biliary tract is arc surface first, head surface is smooth；Light Sliding arc surface head can make probe movement in biliary tract more smooth, will not stab biliary tract inner wall.

Preferably, the tail portion middle section is handle, handle is equipped with anti-skid chequer；Anti-skid chequer is equipped on handle It can be convenient healthcare givers's operation, prevent from sliding in biliary tract when biliary tract bougie is mobile, bring discomfort to patient.

Preferably, the probe, feeler lever, tail portion are sequentially connected；Probe is connected for protruding into biliary tract intramedullary expansion biliary tract Feeler lever at probe rear portion plays guiding and guarantees that the movement of probe is more stable, is connected to the tail portion at feeler lever rear portion convenient for medical treatment Probe is taken out and protrudes into the operation of personnel.

Preferably, the probe, feeler lever and the diameter of tail portion ratio are 3:1:2；The probe, feeler lever and tail portion Length ratio is 1:5:2；It is bigger with the contact area of biliary tract inner wall when the probe of major diameter moves inside biliary tract, reach biliary tract Better expansion effect；And the feeler lever of longer dimension can guarantee that probe can penetrate completely one time in biliary tract.

Detailed description of the invention

Fig. 1 is a kind of structural schematic diagram of biliary tract bougie embodiment of the utility model；

Fig. 2 is a kind of structural schematic diagram of biliary tract bougie in the present embodiment；

Fig. 3 is the structural schematic diagram popped one's head in the present embodiment；

Appended drawing reference: 1, it pops one's head in；10, head；2, feeler lever；3, tail portion；30, handle.

Specific embodiment

The utility model is described further with reference to the accompanying drawing.

A kind of biliary tract bougie as shown in Figures 1 to 3, feeler lever 2, Yi Jilian including including probe 1, the connection probe 1 Connect the tail portion 3 of the feeler lever 2；Probe 1 protrudes into the head 10 that one end in biliary tract is arc surface；3 middle section of tail portion is handle 30。

As shown in Figure 1, healthcare givers holds biliary tract bougie tail portion 3, probe 1 is protruded into biliary tract slowly, probe 1 is being visited It is protruded under the action of bar 2 along biliary tract inner wall, since the maximum value of 1 diameter of probe is greater than 4mm, and 1 length direction ruler of probe Modest ability degree is greater than the diameter of probe 1, increases when probe 1 moves in biliary tract with the contact area of biliary tract inner wall, can be by biliary tract The flat place of pine and contraction place in inner wall support, and are effectively expanded biliary tract inner wall, so as to import drainage tube into The surgical work of row next stage；Avoiding the inadequate and small-sized probe 1 of the small-sized contact biliary tract area of probe 1 can not support Phenomena such as flat place of pine of large area and contraction place, thus greatly reduce successful surgery.

3 middle section of tail portion is handle 30, and handle 30 is equipped with anti-skid chequer, when healthcare givers holds handle 30, handle 30 On anti-skid chequer convenient for healthcare givers's operation, while increasing the friction of hand Yu handle 30, prevent biliary tract bougie from sliding into biliary tract It is interior, discomfort is brought to human body.

As shown in figure 3, probe 1 protrudes into the head 10 that one end in biliary tract is arc surface first, 10 surface of head is smooth；It visits The first 1 arc surface head 10 smooth when protruding into biliary tract will not stab biliary tract interior wall tissue, and pop one's head in 1 in biliary tract inner wall Movement is more smooth.

The above makes preferred embodiments of the present invention, does not depart from for those of ordinary skill in the art Under the premise of the utility model principle, several variations and modifications can also be made, these also should be regarded as the protection of the utility model Range.
