The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1 to 3, the laparoscopic surgery intraoperative measuring tool 100 of the present application includes: the measuring device comprises a handle 101, a measuring ruler 102, a rotating shaft 103, a rack 105 and a rotating fluted disc 104;

wherein, an accommodating cavity 101a for accommodating the measuring scale 102 is formed at the end part of the handle 101, the rotating shaft 103 is arranged at the end part of the handle 101, and the measuring scale 102 and the rotating shaft 103 are in rotation stopping connection; a through groove 101b is formed in the handle 101, and the rotating shaft 103 protrudes from the through groove 101 b; the rack 105 is arranged in the through groove 101b, and the rack 105 is sleeved on the through groove 101 b; one end of a rack 105 is meshed with the rotating shaft 103, and the other end of the rack is meshed with the rotating fluted disc 104; scales are provided on the measuring scale 102. As such, when performing laparoscopic surgery, it is often necessary to measure the lesion in the abdominal cavity to facilitate subsequent surgical operations.

For this, the measuring tool in laparoscopic surgery protected by the present application is constructed by disposing the measuring ruler 102 on the rotation axis 103. Thus, when the measuring scale 102 extends into the abdominal cavity of a patient, the measuring scale 102 rotates into the cavity 102a, and at the moment, the measuring scale 102 and the handle 101 are mutually overlapped, so that the measuring scale 102 can enter the abdominal cavity under the condition that the opening formed on the abdominal cavity of the patient is small; then through the drive dipperstick 102 rotation of rotating fluted disc 104 again, dipperstick 102 will rotate to the horizontality in patient's abdominal cavity this moment, and then can measure stretching open dipperstick 102.

In addition, in actual measurement, the measuring scale 102 is usually rotated to measure different angles in order to measure different angles, but only the handle 101 is rotated, and the angle that the measuring scale 102 can provide is limited, and therefore, in the present invention, the measuring scale 102 can be rotated to provide different measuring angles in accordance with the rotation of the handle 101.

Furthermore, the measuring scale 102 is rotated to an angle perpendicular to the handle 101, so that when the measuring scale 102 enters the abdominal cavity, the opening of the abdominal cavity only needs to be consistent with the opening of a conventional laparoscope; however, the situation inside the abdominal cavity is complicated, and if the length of the measuring scale 102 is too long, the measuring scale 102 will mark a large sector area inside the abdominal cavity when rotating from an angle overlapping the handle 101 to an angle perpendicular to the handle 101 inside the abdominal cavity, which is likely to scratch the internal organs inside the abdominal cavity.

To this problem, this application sets up dipperstick 102 into the telescopic form, so the whole length of dipperstick 102 can set up short, after dipperstick 102 rotated to the angle perpendicular with handle 101, the angle of dipperstick 102 is prolonged again, so just can guarantee dipperstick 102.

Therefore, the specific scheme is as follows:

a push rod 106 is arranged on the handle 101 in a sliding manner, the push rod 106 can be inserted into the accommodating cavity, a push block 1061 is connected to the push rod 106, and an inclined surface matched with the push block 1061 is arranged on the measuring scale 102; thus, when the measuring scale 102 is folded into the accommodating cavity, the pushing rod 106 is moved to push the pushing block 1061 to push the measuring scale 102 outwards, and the rotating shaft 103 is rotated, so that the measuring scale 102 is pushed to be perpendicular to the handle 101. The key factors for achieving this operation are: the friction among the rotating shaft 103, the rack 105 and the rotating fluted disc 104 is very small; as the push rod 106 is moved, the rotating toothed disc 104 is also rotated. Thus, expanding the dipstick 102 in this manner ensures that the dipstick 102 is expanded in one direction each time.

Furthermore, the rotating fluted disc 104 is provided with a pointer, and the handle 101 is provided with a scale, when the pointer and the scale are overlapped, the measuring scale 102 is indicated to be in a vertical position with the handle 101.

Further, a cavity 102a is arranged in the measuring scale 102, a telescopic scale 1021 is arranged in the cavity 102a in a sliding manner, a screw hole 102b is arranged on the telescopic scale 1021, a screw 1022 is screwed in the screw hole 102b, a first bevel gear 1023 is arranged at the end of the screw 1022, a second bevel gear 1024 is further arranged on the measuring scale 102, and the second bevel gear 1024 and the first bevel gear 1023 are meshed with each other; a guide protrusion 102a1 is provided on the inner wall of the cavity 102a, a guide groove 1021a is provided on the telescopic scale 1021, and the guide protrusion 102a1 is engaged in the guide groove 1021 a; in this way, after the second bevel gear 1024 is rotated, the telescopic scale 1021 can be extended from the measuring scale 102, and the length of the measuring scale 102 can be controlled.

Further, the second bevel gear 1024 protrudes from the inside of the measuring ruler 102, a rotation stopping sleeve 1025 is arranged on the second bevel gear 1024, and the section of the rotation stopping sleeve 1025 is selected to be rectangular in the embodiment; the push rod 106 is provided with a rotation stopping rod 107, and the rotation stopping rod 107 is arranged on the push block 1061 in a sliding manner; thus, after the push block 1061 pushes the measuring ruler 102 to be perpendicular to the handle 101, the rotation-stopping rod 107 moves towards the rotation-stopping sleeve 1025, and the rotation-stopping rod 107 can be inserted into the rotation-stopping sleeve 1025; the rotation of the rotation stop lever 107 can guide the measuring tape 102 to move out of the measuring tape.

Further, the following description will be made of a scheme for moving the rotation preventing lever 107

Referring to the drawings: the rotation stopping rod 107 is connected with a fixed sleeve 108, the fixed sleeve 108 is connected with a guide rod 109 and a driving rod 110, the pushing block 1061 is provided with a guide hole for the guide rod 109 to pass through, the driving rod 110 passes through the pushing block 1061, and the driving rod 110 is rotatably connected with the pushing block 1061; a plurality of transmission gears 1062 are arranged on the pushing block 1061, a threaded sleeve 1101 is sleeved on the driving rod 110, threads meshed with the threaded sleeve 1101 are arranged on the driving rod 110, and the threaded sleeve 1101 and the adjacent transmission gears 1062 are meshed with each other; the transmission gear 1062 extends to one side of the push rod 106, a driving tooth 1063 is sleeved on the outer side of the push rod 106, and the driving tooth 1063 is meshed with the adjacent transmission teeth; thus, the screw sleeve 1101 can be rotated by driving the push rod 106 to rotate, so that the driving rod 110 can move back and forth.

Further, the following describes the technical scheme for driving the rotation stop lever 107 to rotate

Referring to the drawings: the rotation stopping rod 107 is rotatably connected with the fixing sleeve 108, a rotating hole 108a is formed in the fixing sleeve 108, the rotation stopping rod 107 is partially inserted into the rotating hole 108a, the rotation stopping rod 107 is further connected with a transmission rod 111, the transmission rod 110 is arranged in a hollow mode, one end of the transmission rod 111 is connected with the rotation stopping rod 107, the other end of the transmission rod 111 is inserted into the hollow part of the transmission rod 110, a slot 110a is formed in the transmission rod 110, a rotation stopping gear 1111 is sleeved on the transmission rod 111, a driving gear 1064 is arranged on the pushing block 1061, gear teeth of the driving gear 1064 adjacent to the rotation stopping gear 1111 are inserted into the slot 110a to be meshed with the rotation stopping gear 1111, and therefore the transmission rod 111 can be driven to rotate after the driving gear 1064 rotates. In order to ensure that the rotation stopping gear 1111 and the driving gear 1064 can be engaged with each other when the driving rod 110 moves, the slot 110a is provided with a sufficient length, and the teeth of the driving gear 1064 are inserted into the slot 110a in the moving interval of the driving teeth, so that a space is reserved for the teeth of the driving wheel 1066 by the slot 110 a. Furthermore, the push rod 106 is a hollow tube body with two ends penetrating through, the push rod 106 is rotatably provided with a rotating rod 1065, the end of the rotating rod 1065 is provided with a driving wheel 1066 with the driving gears 1064 engaged with each other, so that after the rotating rod 1065 rotates, the driving wheel 1066 drives the driving gear 1064 to rotate, and then the driving gear 1064 drives the rotation stopping gear 1111 to rotate, so that the transmission rod 111 starts to rotate, and then the rotation stopping rod 107 is driven to rotate; in this way, the telescopic scale 1021 is projected out from the end of the measuring scale 102.

Referring to the drawings, in setting, scales may be set on both the measuring scale 102 and the telescopic scale 1021, and then the measurement is completed; the rotating rod 1065 guides the second bevel gear 1024 to rotate in a rotating manner, so as to drive the first bevel gear 1023 to rotate, thereby pushing out the telescopic rod in a manner of matching with the threaded screw 1022. Therefore, scales can be arranged on the transmission rod 111, namely the extending length of the telescopic scale 1021 can be quantified by the number of turns and the number of degrees of rotation of the transmission rod 111; therefore, when the telescopic scale 1021 is extended, it is conceivable to quantify the amount of extension and contraction of the telescopic scale 1021 by the rotation lever 1065; however, when measuring, the rotation-stopping rod 107 needs to be pulled out from the rotation-stopping sleeve 1025 to ensure that the measuring scale 102 can rotate; therefore, it is necessary to avoid that the rotation preventing lever 107 is inserted into the rotation preventing sleeve 1025 when the rotation preventing lever 107 and the rotation preventing sleeve 1025 are rotated by an erroneous operation to change the angle of the rotation preventing lever 107 and the rotation preventing sleeve 1025 with respect to each other during the measurement.

The following schemes can be adopted in design to avoid

The first scheme is as follows: the rotation stopping gear 1111 can move along with the driving rod 110, namely after the driving rod 110 drives the rotation stopping rod 107 to be pulled out from the rotation stopping sleeve 1025; the rotation stopping gear 1111 will be separated from the driving gear; at this time, if the rotating lever 1065 is rotated, the rotation stop gear 1111 cannot be rotated by the driving gear 1064; and the driving lever 110 is not rotated. Based on the scheme, the scheme is that the rotation stopping gear 1111 is connected with the transmission rod 111. Thus, when the driving rod 110 moves, the rotation stop gear 1111 also moves.

The second scheme is as follows: after the rotation stopping rod 107 is pulled out of the driving sleeve, the rotation stopping rod 107 and the fixing sleeve 108 are in a rotation stopping connection state; thus, when the rotation lever 1065 is rotated again, the rotation lever 107 cannot be rotated because the rotation lever 107 is fixed.

Specifically, the structure of the second scheme is as follows:

the rotation stopping gear 1111 is connected with the transmission rod 111 in a rotation stopping manner, the rotation stopping gear 1111 can slide on the transmission rod 111, referring to the drawing, the rotation stopping gear 1111 and the driving gear 1064 are meshed with each other, meanwhile, a limiting plate is further arranged on the driving gear 1064, and a limiting groove is arranged on the rotation stopping gear 1111, so that under the limiting of the limiting plate and the limiting groove, the rotation stopping gear 1111 cannot move along with the movement of the driving rod 110; therefore, when the driving rod 110 moves, the driving gear 1064 and the rotation stopping gear 1111 can be always meshed with each other.
