Abstract

A living cell transplanting device has a flexible tube capable of accommodating living cells and a cell pushing shaft inserted into the tube. The tube has a lumen penetrating therethrough and a reduced diameter front end open portion. The shaft has a small diameter end portion having a diameter smaller than that of the reduced diameter front end open portion and an enlarged diameter portion having an outer diameter larger than an inner diameter of reduced diameter front end open portion. Owing to contact between the enlarged diameter portion of the shaft and the reduced diameter front end open portion of the tube, a progress of the shaft is regulated. By pushing the shaft into the tube after the contact between the enlarged diameter portion and the reduced diameter front end open portion finishes, the enlarged diameter portion of the shaft passes through said reduced diameter front end open portion with expanding the reduced diameter front end open portion of the tube and projects beyond the reduced diameter front end open portion of the tube.

Abstract

A living cell transplanting tool (1) is provided with a flexible tube (2) capable of accommodating living cells (12), and a cell pushing-out shaft (3) which is inserted into the tube (2). The tube (2) is provided with a penetrating lumen (24) and a diametrically contracted tip end opening portion (23). The shaft (3) is provided with a small-diameter tip end portion (32) having a smaller diameter than the diametrically contracted tip end opening portion (23), and an enlarged diameter portion 33 having a larger diameter than the diametrically contracted tip end opening portion (23). Insertion progress of the shaft (3) is restricted by the enlarged diameter portion (33) of the shaft (3) coming into contact with the diametrically contracted tip end opening portion (23) of the tube (2), and after the two have come into contact with one another, by the shaft (3) being pushed in, the enlarged diameter portion (33) causes the diametrically contracted tip end opening portion (23) to widen by being pushed, passes through the same, and protrudes from the diametrically contracted tip end opening portion (23) of the tube (2).

Abstract


A needle employs a three-stair-stepped structure
including a front-end small diameter part, an intermediate
part, and a large diameter part . The front-end small diameter
part and the intermediate part are in fluid communication with
each other by the first tapered part, and the intermediate
part and the large diameter part are in fluid communication
with each other by the second tapered part. The internal
diameter of the front-end small diameter part is made so as
to be equal to or greater than 0.35 mm based on the allowable
deformation level of a cumulus oocyte complex, the outer
diameter is made so as to be equal to or smaller than 0.7 mm
based on the size of a small follicle, and the inclination
angle of the inclined acicular end, and the length is made
so as to be 10-25 mm based on the size of a dominant follicle.
The internal diameter of the intermediate part is made so as
to be equal to or greater than 0.45 mm based on the size of
the cumulus oocyte complex. The internal diameter of the
first tapered part is formed at an average gradient of equal
to or smaller than 10% so as to suppress an abrupt recovery
of the cumulus oocyte complex from a deformed condition at
the time of suction, and the total length from the front-end
small diameter part to the intermediate part is made so as
to be a length that does not allow the large diameter part
to be inserted in human tissue.

Abstract

A needle is formed in a three-part structure composed of a small-diameter tip part, a middle part and a large-diameter part, wherein the small-diameter tip part is fluid-communicated with the middle part through a first taper part and the middle part is fluid-communicated with the large-diameter part through a second taper part, the small-diameter tip part is so formed that the inner diameter is set at 0.35 mm or more on the basis of the allowable deviation of a cumulus cell, the outer diameter is set at 0.7 mm or less on the basis of the size of a small follicle and the inclination angle of an inclined tip and the length is set at 10 to 25 mm on the basis of the size of a dominant follicle, the inner diameter of the middle part is set at 0.45 mm or more on the basis of the size of a cumulus cell, the inner diameter of the first taper part is so set as to have an average grade of 10% or less in order to prevent the rapid deformation recovery of an oocyte-cumulus cell complex during suction, and the total length between the small-diameter tip part and the middle part is so set that the large-diameter part cannot penetrate through a tissue of a human body.
